Hi Jamal,

We understand that the 100% Disk usage is affecting the performance your computer. We would like to know what application in the Task Manager is consuming the most Disk usage. If possible, kindly provide us a screenshot of all the process in Task Manager. There may also be a third party program running in the background that is causing the issue. We recommend that you perform a clean boot to see if the Disk usage will go down while your third party apps are disabled.

We'll be waiting for your response.

Thank you for your reply it's affected by more than one program sometimes the System may cause this another times it's affected by Service Host:Super fetch, and windows explorer other times it's due to Service Host:Cryptography services and other programs by the system but it's rarely to be caused by a third party program.

I've tried to disable Service Host:Super Fetch and windows explorer but that didn't help.

Furthermore, When the Disk is 100% in use only (0.2-3)MBs are used !

Hope You solve my problem.

Thanks in Advance

Got 100% disk usage in Windows 10? So your computer is hanging and freezing. Same old Windows, right? Except you’re using a brand-new Windows 10 device; you’ve only had it a few days. So just what is going on?

Investigating, you discover that your system drive is running at 100%. Surely this can’t be, right? Sadly, it is. The latest versions of Windows have a problem with the drives being overworked, which slows down the operating system. This issue affects both hard disk drives (HDDs) and solid-state drives (SSDs).

Several fixes are available for this, but first you need to trace the problem.

100% Disk Usage in Windows 10: Fixed!

When the error was first discovered, only a few culprits were found. But as time passes, despite the 100% disk usage error being reported to Microsoft, more causes of this bug are discovered, not fewer.

Click the link above for each possible cause of the bug to see how to fix it.

Once you’ve established that there is a problem, you have several options available. Check the following steps one at a time, checking the disk usage in the Task Manager after each.

Note that even if you find a solution, a Windows Update could reset the changes you’ve made. Bookmarking this page will help you find it in future to run through the fixes again.

1. Slow Performance? Run Disk Check

This performance issue is most obvious when attempting to use Windows Search to find a file or program, and anything else that requires the drive to do some work (perhaps copying and pasting a group of files).

To establish whether it is a problem that is affecting you, when your computer next slows down press Ctrl+Alt+Del and select Task Manager10 Windows Task Manager Tricks You Didn't Know10 Windows Task Manager Tricks You Didn't KnowIf the only time you open the Task Manager is when an application is frozen and needs to be killed, you're overlooking some of its more powerful features.Read More.

(Alternatively, right-click the Taskbar and select Task Manager.) Note that this may take some time to open with the drive being under strain.

On the first tab, Processes, look for the Disk column. If you’re having problems with drive performance14 Ways to Make Windows 10 Faster and Improve Performance14 Ways to Make Windows 10 Faster and Improve PerformanceIt's not hard to make Windows 10 faster. Here are several methods to improve the speed and performance of Windows 10.Read More, this should be at 100%, and shaded red to indicate whether you have a problem or not.

Problematic sectors on your HDD can cause the 100% disk usage issue in Windows 10. However, using Windows’ built-in disk check can fix this.

Open Windows Explorer and select This PC, then identify your hard drive. Right-click on C: and select Properties. Here, find the Tools tab, and under Error checking click on Check.

In the resulting window, click Scan drive. Wait while the system scans the drive; a reboot may be required for a full disk repair. This should deal with the error.

2. Check Your Anti-Virus Software

As with any such performance issue, the first thing to do is confirm that your computer hasn’t been infected with malware. Your security software should be able to deal with this, whether it’s a free app or a paid suite.

At the very least, tools such as Malwarebytes Anti-Malware should be able to scan your system drive and detect any problems, although with a heavy load on your drive already this may take a while.

If threats are found, use the software’s recommendations to discard them and reboot. Next, check your drive’s performance further. Hopefully, you’ve resolved the issue; if not, then malware wasn’t to blame, so read on.

3. Disable Windows Search for Improved Disk Performance

The next thing to check is whether the 100% disk usage error has anything to do with Windows Search.

A bug in Windows 10 results in a “search loop” that causes an increased load on the system drive.

To stop this and prevent it from happening during your current session (until Windows is rebooted) open the Command Prompt (the quickest way is by clicking the Start button and typing cmd, then right-click and select Run as administrator) and enter:

To permanently disable Windows Search or Indexing, press WIN+R, enter services.msc, and hit Enter. In the Services window that opens find the Windows Search entry and double-click it to open the Windows Search Properties window.

Under Startup type, select Disabled. Here you can click Stop to abort the service. Click OK to save your changes.

A few moments after disabling Windows Search, your Windows 10 performance should improve considerably. If not, move on…

4. Disable Superfetch Service

Another Widows 10 feature that has been identified as a potential cause of the 100% disk usage issue is the superfetch serviceWhat Is Superfetch on Windows 10? And How to Disable ItWhat Is Superfetch on Windows 10? And How to Disable ItIs the Service Host: Superfetch causing high disk usage in Windows 10? What is Superfetch and can you disable it? Let's find out.Read More.

To deal with this, open another Command Prompt (or if you’ve still got the earlier box open, use that) and enter:

Again, wait a few moments to check whether this has had any effect on your computer’s performance. You should also run Check Disk in a Command Prompt:

You’ll be informed that your PC must be rebooted for Check Disk to complete, so make sure you have closed all your applications first.

If this doesn’t work, it is likely that you’re experiencing an iteration of this issue that is frustrating to realize, but simple to resolve.

5. Is Flash Causing the 100% Disk Usage Bug?

Flash remains one of the most vulnerable aspects of modern computing and should be disabled. Adobe plans to kill off its multimedia plugin in 2020, so there’s little reason to keep using it.

Flash also seems to be one of the most common culprits for the 100% hard disk usage in Windows 10 if you’re using the Google Chrome browser.

Open Menu > Settings > Show advanced settings and find the section marked Privacy. Here, click on Content settings and find Flash. You’ll see a toggle, so set it to Block sites from running Flash, then click Back.

Restart the browser and check your HDD performance.

6. Use a Different Web Browser

It may not be Flash that is impacting on your browser performance.

Another cause could be the browser itself, particularly if you’re using Google Chrome.

The obvious option is to choose a different browser. Windows 10 already has two browsers built in. You probably don’t want to use internet Explorer, but Microsoft Edge is an adequate replacement for Chrome.

Several browsers are available, some better than others. See our guide to the best web browsers for WindowsThe Best Web Browsers for WindowsThe Best Web Browsers for WindowsWhat is your default web browser?

7. Is Skype Eating Disk Resources?

Another widely-used application could also be causing your 100% HDD usage: Skype.

To find out—and disable its OTT resource requirement, begin by checking that the software is not running. You can do this by looking in the Task Manager, or checking the System Tray, the area on your desktop around the clock. If Skype is running here, right-click the icon and select Quit.

Next, press WIN+R and paste this address into the box:

Click OKto find the Skype.exe file and right-click this and select Properties. In the Security tab click Edit, then select ALL APPLICATION PACKAGES.

Put a check next to Write in the Allow column and finish off by clicking Apply, then OK. Head back to the Task Manager to see the change.

8. Resolve PCI-Express Firmware Bug

Some drivers don’t run quite as they should in Windows 10. One that has been discovered to be causing 100% HDD use is the StorAHCI.sys driver, which has a firmware bug. StorAHCI.sys intended for storage devices connected to the PC or laptop motherboard via Advanced Host Controller Interface PCI-Express.

If you’ve made it this far with no success, this could be the problem.

Open the Device Manager (use Windows 10 search, or right-clickThis PC in Windows Explorer, then Properties > Device Manager) and expand IDE ATA/ATAPI Controllers. If an AHCI Controller entry is listed, double-click, then open the Driver tab and select Driver Details.

Is the driver listed as C:Windowssystem32DRIVERSstorahci.sys? If so, you could be affected by this bug.

Close the driver details box and switch to the Details tab, selecting Device instance path from the drop-down menu. Where the Value is listed, right-click, and select Copy. Launch your text editor (like Notepad) and Paste the contents in.

Next, press WIN+R and type regedit, followed by the OK button. Navigate to this address: HKEY_LOCAL_MACHINESystemCurrentControlSetEnumPCI and use the pasted string above to open the correct AHCI Controller, followed by the random number.

Here, expand Device ParametersInterrupt ManagementMessageSignaledInterruptProperties and you should see MSISupported listed in the right-hand pane. Double-click this, then change the Value data: to 0. Click OK to confirm and follow the instructions to restart Windows.

9. Is Steam Maxing Out Your HDD?

Enjoy gaming and have Steam installed? There’s a good chance this digital delivery system is causing 100% disk usage.

Usually this is due to update delivery, causing the background downloader to get caught in a loop. Clear the Steam cache to fix this.

First, make sure you have exited Steam. Where Steam is a likely cause of the 100% disk usage error, it may hang when you try to exit. In this case, use the Windows 10 Task Manager to close the software.

Next, open the WIN+R run box and enter

You’ll see a dialogue box, informing you that content will be deleted.

Click OK to proceed.

Note that games and saves will be retained, so there is no risk of them being deleted.

10. Disable Diagnostic Tracking in Windows 10

Finally, it’s worth considering the impact of diagnostic tracking in Windows 1013 Windows Diagnostics Tools to Check Your PC's Health13 Windows Diagnostics Tools to Check Your PC's HealthUse these computer diagnostic tools to run a PC health check and fix issues. Some support Windows 10 diagnostics, specifically.Read More. A feature that you might have otherwise disabled for privacy reasons, it has been blamed for 100% HDD use on many PCs.

When it comes to reducing your hard disk drive usage, it’s quicker to simply disable the DiagTrack service. If this is the source of the 100% disk usage error in Windows 10, you can stop the service launching.

However, to do this you’ll need to access Command Prompt in administrator mode.

Do this by clicking Start and typing cmd in the search box. Wait for the results and right-click Command Prompt, selecting Run as administrator.

Right-click the Start button and select Command Prompt (Admin), then input these commands to disable and stop DiagTrack:

In addition, you might also head to Settings > System > Notification & actions and disable Get tips, tricks and suggestions as you use Windows. Doing so has been shown to improve things.

11. Windows Update Can Cause High Disk Usage

As well as affecting changes you make to your PC when fixing the 100% disk use problem, Windows Update can also be a cause.

This usually only happens when Windows Update has a problem (which is typically due to a file refusing to download). You have two options here:

1. Leave your computer alone—shut all your open applications and wait. Eventually, the files will download, but depending on how Windows Update is scheduled on your computer, it may require a reboot.
2. Shutdown your computer—once you’ve done that, restart and wait for Windows Update to resolve the problem.

Once the update has finished downloading, it’s wise to run it as soon as possible. Remember to check any previous fixes for 100% disk usage before proceeding; as noted above, Windows Update can reverse these fixesHow to Resolve Windows Update Problems in 5 Easy StepsHow to Resolve Windows Update Problems in 5 Easy StepsHas Windows Update failed you?

Here's how to set the virtual memory size and boost performance.Read More is a combination of RAM and hard disk space and can be responsible for overuse of your HDD. If there isn’t enough RAM to perform a task, the HDD is used to supplement the RAM. Data moved to the HDD is then returned to RAM when required.

If you’ve made it this far and you’ve yet to solve the 100% disk usage issue, it could be worth resetting your virtual memory.

Open the System screen with Windows+Break/Pause, then Advanced System Settings on the left. In the resulting box, select the Advanced tab, then under Performance click Settings.

Here you’ll find another Advanced tab, which has a section labeled Virtual memory. Click Change and clear the checkbox for Automatically manage paging file size for all drives.

Staying on this screen, select your Windows drive (usually C:) and then Custom size. Here, add an Initial size and a Maximum size; note both are measured in MB rather than GB.

These numbers can be confusing, so with the first value, rely on the recommended option. For the maximum value, aim for a figure no more than 1.5 times your system RAMEverything You Need to Know About RAM & Memory ManagementEverything You Need to Know About RAM & Memory ManagementRAM is your computer's short term memory. Hence, memory management has a significant impact on system performance. Here we explain how RAM works and whether you can do anything to increase its efficiency.Read More.

For instance, a computer with 4GB of RAM should have no more than 6.5GB (6144MB).

With the values input, click Set, then OK to continue. You now need to clear the temporary files that have been used in the previous virtual memory allocation.

Do this by opening the Run box (WIN+R) then entering “temp”. When the temp directory opens, select all files (Ctrl+A) and tap Delete on your keyboard.

13. Activate High Performance Mode

Free Disk Usage Utility

One final thing to try is altering your Windows power settings. Download windows 7 free. Standard power modes are more prone to the 100% disk usage bug but switching to high performance often overcomes the problem.

The downside, of course, is that your computer will use more power. Thanks to modern processor design this shouldn’t be a massive issue. However, notebooks and desktop replacement laptops may take a hit on battery life.

If this isn’t a displayed option, you’ll need to create your own custom power plan. Click Create a power plan, then choose High performance. Give the plan a name, tweak any personal settings you need then select it as a power plan to use.

In a moment or two, the 100% disk usage issue should drop down to less than 10%.

14. Install the Latest SATA Drivers

Could a storage device driver be resulting in the 100% disk usage error?

Your Windows 10 computer almost certainly uses SATA connections for hard drives, SSDs, and optical drives. If the drivers aren’t up to date, the disk usage error can occur.

Avoid this by upgrading to the latest SATA drivers.

Open the Power User menu with WIN+X and select Device Manager. From here, expand Storage controllers, then identify the correct controller for your SATA devices. If you can’t do this, don’t worry—simply update both.

To update, right-click on each controller and select Update driver.

Select the Browse my computer for driver software option, then Let me pick from a list of available drivers on my computer. Here, choose Standard AHCI Controller and see how this impacts performance.

You may need to reboot Windows for this to take effect. Note that if it doesn’t work, you can still try this by checking the manufacturer’s website for a new driver. This can be installed using the instructions that accompany it.

Disk Usage Should Rarely Be 100%

Put simply, there is little reason for your disk load to be anything close to 100%, certainly not under normal usage. A slow computer is one with a problem, and if you cannot fix it by disabling a browser plugin, stopping services, or running your antivirus software, then the problem may well be hardware related.

Perhaps your drive is getting old; it may be defective, or the cables may need replacing. Alternatively, there is a chance that the problem is connected to the Windows defrag tool.

If your computer is attempting to defrag your drive, but your HDD is actually an SSD, then serious problems can occur. Deal with this by opening the Task Scheduler (WIN+Q, enter “task scheduler”) and disable any scheduled disk defrag tasks.

Unix Disk Usage

1. I have had 100% Disk Usage issues with various laptops since 2017! I know all the tricks by heart now. It seems like only a matter of time before everyone running Windows 10 will get this issue. Question: Why is Microsoft so inept at fixing this frickken issue! They have known about this issue FOR YEARS!! Yet they cannot fix it? Argh!!!!

2. Number 3, Disable Windows Search for Improved Disk Performance, solved it for me. The difference is night and day. Thanks!

3. Disabling Windows Search, Windows Diagnostic and Disk Defragment Tool, did the work for me. Thank you!!!

4. Sadly, not one worked for me.

5. Can't suggest this enough! Worked amazingly

6. Incredible!
   i thought nothing would solve my disk problem which was making my PC unbelievably slow until i found this. I followed everything, restarted and the disk % and the speed of my computer were fixed. Can't suggest and thank this post enough

7. Thank you.. the windows search option worked for me!

8. Holy sh*t, your a hero my disk space went down to 6% after this

9. Thx you very much for this post, he helps me.

10. Worked great, my partner had a new laptop which ran like ass. In doing all 10 of these we finally got it jumping from between 0% - 40%.

    Thank you.

11. None of these worked for me but I was finally able to fix it.

    11. Install latest SATA Drivers for your motherboard.
    Since I was running a Clean install of Windows 10 I had troubles with my Hard Drives. I Installed all drivers for sound, graphics, WLAN, all the good stuff. Since basically everything was running great I thought my HDD was dead. Bought a new one, same problem. Finally, I started looking for Motherboard updates for my Asus Prime and found that there was a separate installation for the SATA Drivers. Installed it and both the old and the new HDD are running GREAT AGAIN.

    If all else has failed, this could be your problem too.

12. Worked for me! Thanks!!!

13. Wow! Surprisingly, after trying most of these fixes, it was disabling the scheduled disk defrag tasks (not even one of the numbered items on the list) for my HDD that resolved the disk utilization issue. It is mostly staying below 5% now. Thanks!

14. Thanks !! disk usage just fall from 100% to less than 20% !

    thanks for the tips, really helped, hope my laptop will work better now :')

15. Thank yo uvery much

16. Or your computer is a Hewlett-Packard, in which case you need an aggressive lawyer.

17. HAve disabled Windows Search, Superfetch and all others mentioned in the suggestion. But it keep coming back again and again.
    Any permenent solution?

18. I went through the 10 steps about a year ago (found the printout last night ) and it solved the problem until Windows did an update. problem started again. so went through the 10 steps again, then disabled automatic updates. for about a month I would get the option to shutdown and ignore the updates. then one night I left the laptop on and the next morning realized updates had been installed that night. the problem started up again and now the option to disable automatic updates is closed. so for 5 months I have had the problem and have tried to pull the internet cable and disable the wireless card so I only connect to the internet when absolutely necessary. when I connect to the internet the disk use immediately jumps to 100% and will not go down until I pull the cable and restart. software says I don't have a virus or malware but there is something happening behind the scene. I think MS updates are working against the fixes that are being published. I now disconnect from the internet and never leave the unit on when not in use.

19. I tried everything, I mean everything to fix the 100% disk usage on start up and very poor performance. It wasn't until I switched from the HDD drive that came with the laptop to a SSD answered my problems. Since switching my boot time went from several minutes to just a few seconds. If you have tried all of these solutions and still no luck, spend a little on a new SSD drive. Just clone your OS onto the SSD and slap that one in. Your stress level will vanish after doing so.

20. i do some defragment on my c and voila, the usage go down to 0%. try this if you have old disk :)

21. I've been having the 100% disk problem on my laptop since I upgraded to Windows 10 and I've tried every suggestions available. I ended up doing a fresh boot, and still had the same problem. But I noticed that the windows telemetry program keep hogging up my disk space (did not notice this before the boot though). Disabling this works like a charm for now - the disk's performance drop to 0-2%. Hopefully it stays that way!

    • Thank you very much, it also did the trick for me.

22. #2 fixed it for me

23. I have tried all options without big effect, except couldn't run:
    PS C:WINDOWSsystem32> sc config 'DiagTrack' start = disable
    Set-Content : A positional parameter cannot be found that accepts argument 'start'.
    At line:1 char:1
    + sc config 'DiagTrack' start = disable
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo : InvalidArgument: (:) [Set-Content], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.SetContentCommand

    as getting red alert message that smth wrong. Any help with it?

24. My problem appeared to be Steam, I was looking at what was the highest item under disk and it was something for Steam. I closed it and immediately went down from 100% to 2%.

25. VERY HELPFUL! 6 helped me to kill my disk usage from 100% to average 6-7% haha thanks!

    • Is it safe? i am not sure of making registry changes?

26. The 7th tip worked for me.. You are great man thanks for the help..

    Run UninstallWinClient.exe. This program is located in the ldmain share on the Core Server by default (C: Program Files LANDesk ManagementSuite ldmain). It can be run from that share or copied to the local client and executed. It is a standalone program and does not rely on any other files in order to run. Replace '' with the location of the 'UninstallWinClient.exe' file you copied in Step 1. Type 'UninstallWinClient.exe /reboot' into the command prompt and press 'Enter.' This uninstalls the LANDesk client and reboots the machine automatically, so changes take effect immediately. Uninstallwinclient exe landesk management.

27. Thanks Christian, Steps 2 and 3 did the job. it worked perfectly!

28. The disk usage doesn't show any active apps but it's still 100%

29. Hello Christian
    I have tried all of these methods (and a few others from other advisors). None of them worked. I have a new Acer laptop..just 2 months old. It is really frustrating.
    Please help

    • i also have 2 new Acer laptops for myself and my boyfriend tried all steps and nothing has worked.have you figured out a fix?

      • why not u go ask for customer service of acer?

30. Chrome is the mother of disk usage issues

31. My win 8.1 Laptop is doing the same thing and I have tried all your fixes except the one that is only for Win 10 and several worked for a while but the problem comes back. I also have changed my page file several times. I had the thought that there may be a S.M.A.R.T. type program or some other diag running on my hard drive and I looked on the INTERNET for a way to turn it off . I found ONE post and it refereed me to gpedit and going to the disk area I think it was in administration. But my copy of Group policies does not have that. Perhaps that is a windows 10 feature also. I tried to find the site again to check but my computer froze up and I had to cold boot. I have not found my way back to that page. Do you have any idea what I am talking about at all?

32. Hi Christian. I have followed the steps in Number 6 which is to correct the issue with the incorrect driver path, but once I have changed the value for MSIsupported to 0 and clicked ok I am not getting instructions to restart my pc. Does this mean that the changing of the value is not being recognised ?. Thanks

33. after executing the 'net.exe stop superfetch' command line, it worked great, until i closed my screen and walked away for the night and then i opened my laptop back up. laptop locked back up and i was at 100% again. i reentered the command line again and it worked again. is there a way to permanently disable this so i don't have to re enter it every time i open my laptop?

    • You need to stop and disable superfetch from services.

34. On my Apollo Lake Acer laptop, I update my default graphics adapter driver for Intel HD Graphics 505 to the latest official Intel driver and the 100% disk usage problem disappear. I have to upgrade the driver manually through searching the inf file because the vendor's driver prevent it from upgrading - through exe directory.

35. WIth tip 7 my Disk MB/s jumped twenty fold but I'm still at 100% disk usage. But 40 to 50 MB/s is MUCH better than the 2.5 I was averaging. Thank you!

36. Is there perhaps a typo in DiagTrack? I keep getting error that windows doesn't recognize 'start='. This is the only one left to try and I did get a slight reduction to 75% after PCIexpress bug fix, but rebooted and back to 100%. Note in W10 right clicking start button only gives power shell (admin) not command prompt so I used that.

37. Tried them all but no success. Top user of disk is system but don't know more specific.

38. It works, thank you so much ^^

39. Solved with steps 2 & 3. It's like a whole new computer. Thanks!

40. Thanks for such a great article.....
    It really solved my disk usage problem
    All methods which can be found scattered over internet are nicely summed up here

41. For me stopping DiagTrack was dramatic, the disk usage dropped 95% very happy.m

42. so anyway, this problem does NOT mean your hard drive is bad?

43. So i bought a used acer aspire v touch 1tb 8g ram. noticed after a month My disk was running at 100% and it seemed slow so I wiped it .complete fresh windows 10 install with update .was online uploaded some backed files i had saved . Shut it down ..next day power on no boot device found .i paid for acer recommend support because the warranty expire . And they say they think .hard drive needs replaced.?wtd? Now buy new

44. For the PCI-Express Firmware Bug issue, is the value entered in at the end a '0' or a 'D'? It looks like a 'D'. Thank you.

    • Zero.

45. None of these worked. My laptop is brand new and only less than 2 months old
    recently this 100% disk usage was slowing down my system and my work is only by web browsing and a few image editing.
    I doubt its hardware related because its new, all programs are also legit including OS

    any other method we can try before I reformat this OS?

    • If you get any solution on this .
      Please forward it to me on this mail
      rajatm005 @gmail.com

46. thanks :)

47. I go through skype option as mentioned above but it didn't worked then after I end up skype task from task manager and usage dropped to 0 %.

    Thanks.

48. Thanks a lot. This had been a persistent problem for days. It finally got resolved because of the Skype issue. Thanks a ton

49. I did all of these and my disk usage stays very high all the time

50. 7. Disable Diagnostic Tracking in Windows 10 was the culprit with my Windows 10 laptop. Thank you so much for this information!

51. Thank you so much! Disabling 'Windows search' and superfetch did the trick right away. God bless you! (Windows 8.1)

52. This was really helpful. Thank you very much.

53. Disk usage is only 100% when restarting or shutting down. Any of these fixes might help with that?

54. very helpful tips.

55. Thank you sir :) so helpful

56. Really great explanation, but it didnt really fix my problem. In the first 5 minutes I turned on my laptop it has a constant 100% disk usage and then it goes down normal to 0-10%.
    And again after a heavy use such working or playing it goes up to 100% again and goes normal again.
    Can you help?

57. Really helpful - Superfetch was the main culprit

58. Really helpful - Superfetch is the main culprit

59. (cont) Also, son of a b* chrome picked it up again to 100% when I opened that browser after stopping superfetch. Thanks for including the flash disable on this list.

60. Thanks for this! Stoping superfetch seemd to work for me. My disk usage went from 100% to freaking 11%.

61. I did everything on your list and more. When I did the very last thing - turn off auto defrag, my disk usage went to 0%. Now it is bouncing up and down. I am almost afraid to reboot -- for fear it will come back. This is been so frustrating. Thank you so much for the list of things to try. I was about to reload windows - which would have been more of a pain.

62. Thank you SO MUCH for this info. Super fetch was the culprit.

63. It was useful and brought down usage to 1 % but when I restart my computer the Disk usage is back to 100% . Please help .

64. You da real MVP, mate. Thanks!

65. didnt do anything ://

66. First let me say your explanations and procedures were excellent. Despite that it didn't work for me. I have McAfee running on a PC with Windows 10. The hard drive is almost constantly running. Did everything on the list in your page //www.makeuseof.com/tag/4-tips-fix-100-disk-usage-improve-windows-performance/ . The Task Scheduler showed only a McAfee task running* and two Microsoft Tasks, ipoint and itype. I did have an issue with the McAfee program when I went to Windows ten. I had to give them a call, but occasionally I still get a message that pops up saying that the McAfee version is not compatible with the current operating system. But I only see that message about once a month or so. Any advise you could give would be greatly appreciated.

67. work perfectly thnks

68. Disabling search instantly works for me! Great blog! Thanks !

69. Thanks! The disabling Windows search dropped mine from 98% to 5%.

70. Thanks a lot! It worked for me. From 100% I now see it dropped to about ~12%. Basically, I tried every recommendation you gave. :P

71. Well, ive tried many of these, but its still 100% disk usage. I even disabled the super fetch and well, first it helped, but then when I restarted my pc, the 100% came again.

72. Thank you so much, I disabled the super fetch service and my disk usage went down quickly. I noticed that my laptop runs much faster now, thanks for the advice!

73. I have an older Dell Studio 1558 ( Intel Core i5) that I updated to W10 about a year ago. HDD was steadily getting slower and slower. I thought maybe it was time to upgrade to a SSD. After the update ( now just 30 hrs ago) I have seen the 100% disk useage issue. I have disabled several things as explained here and several other sites. Even the Microsoft fix ( disable MSI) has not worked. My computer will run just fine and fast for 15 or 20 minutes but eventually freezes at 100% again. I can't really figure out if something particular sets it off. I have power off rebooted nearly 30 times and it works again for a short while. I even disabled Norton Anti- virus and enabled Defender. I have tried using Edge instead of Chrome also. I checked the SSD firmware, ran a scan for viruses. Nothing has worked. Windows 10 is up to date at 1607. I'm beginning to think that I had this same issue with the HDD but was not quite as severe in freezing up totally. I've run out of things to try. While Apple also has its OS issues, my ipad continues to work!!

74. Got a brand new Inspiron 5000 touch screen 16gb RAM laptop and was so distressed to see this 100% usage issue. I've tried all of the things suggested above and it seems to be working so far. Fingers crossed this will have solved the problem permanently.

75. Thank you very much indeed. Disabled Super Fetch and Disk use went down from 100% to 4%.

76. Thank you! Disk usage went from 99-100% to 1-2% by following your steps. The thing that worked for me was to stop superfetch.

77. I had a physical and mental breakdown when my computer continued to crash.

    I checked all my components and tried rebooting, didn't work.
    so i checked the task manager saw that the 'Disk' usage was at a really high volume so i killed some programs and everything was just fine with rarely any crashes and i wanted to find out how to permanently fix it and i landed on this post and you saved my computer from being absolutely tortured.

78. I went through all these steps, but still had the 100% disk issue. It wasn't until i noticed my sd card reader driver was missing in device manager (listed as 'base system device' instead of the card reader). I went to the lenovo site, downloaded the driver and now my disk usage is very low.

79. Thank you so much. For me, it was Windows search. I permanently disabled it.

80. Thank you SO MUCH for this! The moment I entered the stop superfetch command into PowerShell my disk usage dropped from near-perpetual 99% to about 3-30%. You've saved my life, and probably also my laptop.

81. I have been having a weird issue with my desktop computer. I have a ABS Dreadnought desktop and I keep having 100% disk usage in the task manager. I had first thought it was my hard drive, so I got rid of many different files that I didn't need hoping that would fix the issue. It did not. So then I tried the methods on this page. That didn't seem to work (then again, I'm unsure if I did do it correctly). Then I thought it was Windows 10. So I went ahead and reinstalled Windows 10 on my desktop. (I wanted to use windows 7 but I wasn't using the right version of W10.) After I had done THAT, nothing changed. I still was having the issue. So I had concluded that my HDD was faulty. I ordered a brand new WD Blue Hdd and installed that into my cpu. (I cloned the old HDD onto the new HDD). Nothing changed. Still had that 100% disk usage.

    Please help, you're my only hope now.

82. Hello,

    I tried to fix this problem and after all these instructions and watching a lot of youtuve videos, my diskusage still peaks to 100%. Even when i just start my pc and check diskusage its still 100%.

    • EDIT

      it dropped to max of 30 - 40 % after i changed my energysetup to High performance instead of Energysafing.

      And after i deleted one drive, it dropped till 30% max.

      Hopefully it doenst happen again otherwise, i will add another comment.

      Thank you guys for the comments and this Article, it really helped me!

83. Thanks. It worked. :)

84. I had the 100% disk problem.

    When I uninstalled the Microsoft One Drive software the problem went away immediately.

    This was a new problem for my PC. I sorted the programs on my uninstall list based on most recently added. This had been installed by Microsoft automatically a couple of weeks ago.

    Windows 10
    Toshiba Satellite Laptop

    • It worked. Mate. That Micrsoft One Drive was the real bugger!

    • Same problem and same laptop i will try it ?

    • Thanks a lot
      One drive was the real problem

    • Thank you!! It still works in 2018

85. OMG thank you!!!! Purchased a ASUS ROG laptop for my son and within a week it was running at 100% disc. When i contacted ASUS I was told to do a reset on the computer because it most likely had a virus even though he only had microsoft games loaded on it. Because of this issue the computer would not even do a factory reset or any reset for the matter. ASUS then sent me a USB factory install and because of the issue once the computer entered Windows programs it took 3 days for it to finish install. That did not fix the problem as soon as we turned it on it was perfect but the second we clicked anything BOOM 100% disc usage. Finally I found this article and after disabling 'windows search' and 'super fetch' its down to 2% disc usage and the computer works as it was meant to. Many many thanks.

86. I had a similar issue before my pc would constantly freeze as well. Im not sure exactly what was it that fixed it but all the solutions listed here didnt help but opening my pc tower and changing the sata cord and port helped immensely. Was a little concerned my hard drive i recently bought was faulty.

87. The Superfetch-service was the resolution for me. Thank you

88. I have tried everything in this article and beyond on my son's computer and everytime I reboot, the Disk usage is back up to 100%.

    I have:
    - Disabled Windows Search
    - Disabled Super Fetch
    - Disabled Flash
    - Changed the virtual memory settings a dozen times based on different articles that I have read
    - Updated various settings in Google and Skype

    Any other thoughts?

    Mark

89. This is what worked for me

    1. Open Google Chrome
    2. Goto Settings > Advanced Settings
    3. Click on the Reset Settings button.

    • Thank you so much, I just did this and it worked a charm!

90. Task manager shows 100% disc in windows 10 only when connected to internet through 'huawei mobile partner 3g dongel'. I updated the device with latest driver,but it gives no fruitful result. Please help me.

    • Huawei anything is bad. It is banned by the USA.

91. Awesome thanks. Applied most of the above now it's running well.

92. Thank you so much. Useful article. I was facing this issue from last 4 months. Thank you so much.

93. Win10 laptop w/ SSD, external drive plugged into a USB3 hub. Disk was being accessed by System at a bit less than 2 MB/sec, but nearly continuously. System only used to log weather data, and share the external drive. Disabling superfetch resolved whatever the issue was (chkdsk found No problem with either NTFS partition on the external drive).

94. Hello . Ive tried all of these and my disk is still at 100%

95. Mr. C. Kind Sir, Thank You. Thank You. I followed your easy step by step instructions and BAAM!!
    It seems to me that it worked no more 100% Disk Usage. Wow!! Well now, when windows enlist another update will it relaunch these common conspirators? Will not know for sure but, I will have at arms reach the Master Plan of instructions to reclaim my Disk. Wow! you made the World a better place today.

96. Hello everyone, maybe you can help me, I do not know what to do.

    My pc had windows 7 and upgrade to windows 10.

    Every time I turn on the pc, during the first 20 minutes it is impossible to use it because the disk is at 100% and it is slow.

    After 20 minutes, the pc works excellently even in games.

    It's only 20 minutes, but sometimes I turn it on because I need to use it and it bothers me the fact that I have to wait for this time until the pc starts working correctly.

    What I have noticed, is that, if instead of turning it off, I suspend it, this does not happen.

    It only happens when the pc is turned off. But I can not leave it suspended every day, in addition some updates request reboot, and there is the same thing as turning it off.

    Any Suggestions?

    Thank you!

97. Thank you! I swear I did this before shortly after upgrading to Windows 10, but it looks like a recent Windows Update enabled this once again, causing my Disk usage to get pegged at 100%. All is good in the world once again, so thanks!

98. Go give this video a try, it certainly helped me when the superfetch/Wsearch did not.

99. Great information! laptop was at 100% usage, turned off superfetch, went to 67%. I then turned flash player off and dropped to 3%. What is with these bogus programs????

100. Dell i7 laptop was dead slow. 100% disk. Permanently Disabled Windows Search and in a few minutes, went to 30% and operating normally. A BIG THANK YOU!

101. THANKS! IT WORKED FOR MY WINDOWS 10 LAPTOP :D

102. It work for me.. I stop the WSEARCH service and disabled it for future.. I think using the TASK MANAGER approach is quiet cool. I'm windows 10

103. I have been having this issue only I have not seen mine talked about so here goes.

     I have a 500GB Samsung SSD (Windows is located here) and added a 2TB HDD Toshibia, after my old 1TB failed. The 2TB toshiba will randomly go to 100% disk use and then remain there, this is a new drive with no date on it. The 100% disk use does not seem to be affecting the 500GB SSD at all as task manger only shows the new HHD drive at 100% use, and I can still use and access the main drive. I have updated drivers, changed the cables, and done most of this as I have only been dealing with this issue for the last few days. After adjusting settings as per parts of this article I was able to boot and have the 2TB not be at 100% but as soon as I let the system idle (not go to sleep as I have hat disabled, but let the monitor go to sleep/screensaver) it would go right back to 100%. So any suggestions?.

     This is a custom system I built and have upgraded over the last decade, the last major upgrades (Board, CPU, RAM, Power supply , all change out 1 year ago.
     AMD 64 bit 8 core, Asus board, 32 GB ram, 950w PS (On a work comp at the moment so do not have full specs on me)

104. Thanks for your help, however when I run net.exe stop 'windows search' my disk performance decreases to about 30% but when I reboot my computer the disk is back up to 100% and I have disabled windows search in services. The only way I can stop the 100% is to restart windows search in services then stop windows search at command prompt. Any help would be appreciated.
     Thanks

105. Well, that's a big fat zero on every one of these solutions. I guess Microsoft patched out these fixes.

     • Check microsoft's KB3083595 solution, that fixes drivers issues.

     • KB3083595 Check this microsoft fix.

106. This is incredible: It's a major problem for thousands, probably millions of people. I have for example 2 unrelated W10 machines both having this 100% disk issue. Why do WE have to painstakingly find out the cause. If W10 Task Manager can indicate 100% disk usage, it also should give a list of the most important fundamentally cause-contributing processes/drivers to this 100%, while now it indicates nothing useful. We now have to guess and try and try. The sum of all the work done by these thousands/millions of people to try to get their computer back to the performance level they paid in total many hundreds of millions $/€ extra for is seemingly not convincing to MS to take this issue seriously. They at least could let us know they are working on a generic quality solution and when to expect it.

107. Tried all the suggestions. Still pinned at 100%. Hard drive is not Solid State.

108. Thank you very much for this great article. As my laptop is infected by Cryptolocker Ransomware a few weeks ago, i suspect evrything happen in my laptop as alware. As closing every service from task manager does not solve disk usage problem, i did some google search and stumbled upon this wonderful article. Stopping superfetch and disabling flash plugin solved my problem. Thank you.

109. Disabling flash in chrome cut the disk usage by 70% (I went from 100 to less then 30). so try that first, you should lead with that in the article as well.

110. I've done everything you suggested. It still runs at 100%. My girlfriend's computer does the same. I'm running Windows 10, she is running Windows 7. It SUCKS! I'm thinking about reformatting and going to a Linus OS.

111. I have done all these steps which you have told. But in vain then what I have to do now.

112. I still have this issue.
     It started happening recently. Maybe less than a week ago.
     First I installed one game and it started. It was definitely because of the game at the time.
     I format my disk and installed Windows 8.
     Now, whatever I do it reaches 100% disk in seconds.
     I have tried EVERY solution there is and NOTHING worked.
     Should I just reinstall to Windows 7?

113. Finally! I kept searching 'programs load slowly windows 10', and all I ever got was stuff that didn't work. I finally discovered the disk 100% was the problem, and you gave me solutions that fixed not only that, but my slow program loads. Thank you!

114. Disabling 'Windows Compatibility Telemetry' works for me.

     Great article!

     • Did you do into services to disable it, or did you end the task in Processes?
       Thanks for the help. I've tried everything in the guide and no change :( I'm hoping this will do the trick.

115. I have a Dell Inspiron 3647 with Windows 10 x64 3.00 Ghz and with 4GB RAM installed and my computer is constantly running close to 100%. I tried all the steps above but none worked. My windows search was already disabled as well as superfetch. Windows key plus Q does nothing at all. I ran my Kaspersky Total Security and nothing was found. Any ideas would be greatly appreciated. IF you need any info from me, just let me know.

116. I had tried all of these suggestions (and others from other articles), to no avail. Yesterday, I methodically went through my Device Manager list and checked every single item for an updated device driver. Three or four drivers were updated and I rebooted my laptop. The problem was FINALLY fixed! For all of you still struggling with the 100% disk usage issue, I suggest you try this!

     • + 1 for this solution. Seems to have made a dramatic improvement to my desktop. The one that was killing me seemed to be 'Realtek High Definition Audio'

       Not sure if the problem is completely gone, cross fingers

117. No - nothing fixes the problem - I did a fresh Windows 10 install

118. Flash pluggin disable reduce disk usage more than other solutions.

119. it seems like I don´t have any superfetch..I can´t find it in services and in comand it doesn´t work too

120. If you still have problems try disabling 'Connected User Experiences and Telemetry'. It also takes up a lot of disk usage in your laptop

     Hope it helps.. Thanks

121. If you still have problems try turning off 'Connected User Experience and Telemetry'. It also takes a lot of disk usage in your laptop

     Hope it helps.. Thanks

122. I'm curious how many people having this issue use Trend Micro antivirus software? I've tried all the solutions listed here to no avail. I'm wondering if it's an issue with my antivirus software.

123. In my case I can reproducibly turn disk usage to 100% or to near zero by putting Crashplan Backup to sleep or awakening it, even after limiting it in its settings while 'user is present or active'. Crashplan has a throttle but it is sent to % of CPU activity, not % of disk activity. I have had great problems with this program previously and am not very motivated to fiddle further since I am looking for a replacement when my year is up. Turning off Superfetch and Search services definitely had a good effect also.

124. Hi

     I disabled AVG antivirus and it worked !
     Hope it helps

125. Hi. Thanks for this! It has always helped in the past but since the new Windows 10 update was installed on Saturday, my laptop's been at 100% disk usage and I've only got task manager on.
     I've let my AVG do a full computer scan with no threats detected, stopped the windows search, superfetch, Windows tips and even disabled my flash player but nothing is bringing it down. I read somewhere else that changing the virtual memory can help but it did nothing. I've since changed it back to 'system managed'. Any other suggestions?
     I have a 4GB RAM 64-bit Toshiba Satellite C50.

     • Try checking/updating all of your device drivers. I did this on my Toshiba Satellite laptop and after updating a few drivers and rebooting, my laptop is back to normal again!

       • Hello Donna, how can I check if a device driver is up to date, and if it isn't, how do I update it? Thank you in advance!

         • I don't know if there's an easier way to do it, but what I did was go to Device Manager, expand out each of the categories (so you can see each component), then methodically do a RIGHT click on each item and select 'Update Driver Software'. It will check the installed driver and either tell you that your software is up-to-date, or it will install the new driver. Eventually (after you do this for each of the 10,000 listed components.. OK, that's an exaggeration, but it sure feels that way!), you will probably have to reboot your machine. Good luck, Isabel!!!

         • Hello Donna! I can't seem to reply to your reply, but I just wanted to say I (after much procrastination) tried your method and it worked wonderfully :DDD Thank you very much!

126. Hey. I've tried doing all of these things, but sadly it is not working. I have an HDD, and recently it has been at 100% disk usage a lot. Sometimes it goes Down to 5%, only to jump right back at 100% after a few seonds. My task manager shows that is it my 'System' that does it.
     I have tried searching the web, and I've tried everything I could find there (disabling Windows tips, Search etc-). I've also tried doing the disc scan and repair, but it did not do a thing.
     Now, I am confident that it is not a hardware failure, as my computer is only 1,5 years old and i have been treating it with care.

     What should I try to do now? Any help would be much appreciated :)

127. Idk what else to do. I can get it to 35% idle, but it just shoots back up to 100% randomly. This is so damn frustrating.

128. It went down from 100% to <10% by disabling windows search

129. No luck for me. Disk usage went from 100% to 99%.
     Toshiba Satellite S55-B5280 with Windows 10. Problems began with upgrade from originally installed Windows 8.1.

130. Thanks so much!

     I've been having this problem ever since I got my laptop nearly 2 years ago!
     It was always 100% disk usage at ALL times and I couldn't for the life of me figure out how to fix it. (I did superfetch disable before but it didn't fix it so maybe it was the flash)

     May have been the chkdsk as it was stuck there for nearly 3 hours. After the reboot I'm at around 3% and the start up, there's 0 lag and I can instantly start programs instead of having to wait 10 minutes.

     Thank youuuu!

     So glad!

131. Thank you very much. It really helped!!! Disk usage dropped from 95% to 3%. One small doubt.

     Can we disable the Superfetch too permanently? Or we should stop it every time we start the system?

132. Thank you so much! It was the windows search for me, stopping it worked like a charm! Even a reboot did not help before. So happy I found this article!

133. Settings > System > Notifications & actions > Turn off 'Get tips, tricks and suggestions as you use windows'
     My disk usage dropped from 100% to 2-3% as soon as I did this

     • Thank you! Same here! It worked!

     • it worked :D

134. Disabling Superfetch worked for me! Laptop works like a dream now! Thanks a ton! Bookmarked this site! :)

135. Stopping Superfetch did the trick for me. Thank you so much for this brilliant fix! Laptop works like a dream now! Thanks a lot! :)

136. Stopping 'Windows Search' service worked great. Thanks-a-lot!

137. A combo of stopping superfetch and disabling adobe flash plugin in Chrome helped dramatically. Thanks much!

138. Disabling the flaah seemed to have worked but it not ompletely gone. Disk usage has gone down but occasionally runs to 100% and back down. I don't know if it should be doing that.

139. Thanks. It worked..after superfetch stop.

140. I tried all suggested fixes out there and nothing really worked - I turned off Windows Firewall via services.msc and that seems to have fixed it for me.

     • This has worked straight away for me from 100% - 0% ! Will it affect defence from virus?

       • Hi Bec,

         I believe you should have an antivirus software and a firewall software in place of Windows Firewall - I downloaded a free firewall software and all good so far.

141. I tried all the fixes listed and it's still at 100% antimal ware service executable is the highest maxxing at about 2 mb/s I tried scaning with Windows defender but after 24 hours it was only 1/10 or less the way done (not sure if previous comment posted)

142. I've tried all the fixes listed and it's still a 100%, the highest is Anti-Malware service executable going from 0.1 mb/s to 2, flashing everywhere in between. Also services like steam have trouble using the network but my internet is perfectly fine

143. Thanks it solved my problem. It was due to skype, i followed the tutorial and did the same. It works...

144. As soon as Windows Search was disable the computer performance improved. Disc usage went from 100% to 75% then to 53%. After stopping Superfetch it dropped to 3 to 5 percent. PC performance improve significantly, like is was brand new out of the box.

     One thing I found for Win10 users. If you use the regular CMD prompt you might receive an error 5 when stopping. To resolve this issue, right click on Start and select Command Prod (Admin) click yes to use the Admin prompt and proceed to stop Superfetch.

145. From 100% disk usage down to 2% after using this.!! Thanks so much

146. By far the best and most complete answer to this problem.

147. Disabling flash did the trick for me. Disk usage dropped to 0-2% in idle mode, as opposed to 100%! Thanks for sharing.

148. Thank you!! I did the first one with Windows search and it went from 100% to averaging about 25%. I was getting ready to just send my new computer back from all the crashes..

149. I have tried the fixes above and my win10 machine still gets the 100% issue. Right now it is completely locked. I rebooted, and only have the task manager open, and now the task manager isn't responding. I can only shut down the pc by doing a hard shut down.

150. great tips, helped bring my pc back to life.

151. Disc usage often reaches 100% and the computer shuts down reporting various errors including memory Mgt. Removed Windows 10 & reloaded Windows 8 & problem is now worse. It makes bringing Windows current with 184 updates a near impossible task as many have failed to get installed. Ready to replace this HP laptop which is less than 3 years old..

152. omg thank you very much! it was the flash plugin destroying my disk silently T_T good read anyway. thanks again!

153. An excellent article.

     Disabling Superfetch and Windows Search made no difference for me, but disabling Flash brought down the disk usage from usually 100% to usually <10%

     A warning though. If you're going to run chkdsk, take a backup first ! I ran chkdsk and it hung up at 11%. Luckily, the PC seems to have experienced nothing nasty as a result, but it could have... I imagine I have some corruption from the numerous times in which the entire system has locked up and I've had to hit the Power switch.

     • I had the exact same thing happen to me. However since I was doing this troubleshooting at. Near midnight I figured I'd simply sleep on it and let it do it's thing. When I woke up, it had finished. Disclaimer though, it did not help me solve my issue. My disk usage is still at 90%-100%
       Weird thing is: my computer runs normally. It is not slower nor non responsive. Not sure what is going on there.

       • Exactly the same thing happened to me. And disk usage still too high. Did you find out what was going on?

154. Disabling the flash plug in new Torch seems to have worked! I anticipate tell you how long I've been running 100% disk usage. Now it's hovering around 10-20, one times dropping below 5! Thanks for such a comprehensive guide!

155. Thanks a million. Worked for me after disabling flash plugin

156. Bookmarked.. Best explanation and easy fix.

     thankyou very much.

157. Finally found my culprit! In my case, I had to stop the service 'Diagnostic Policy Service' which was taking 80-90% of my drive. Immediately after disabling, my usage dropped to 5%. Yay! Here's what I learned about this service:

     Using telemetry built into Windows 10, Microsoft sought to improve the features and overall experience of the operating system through automated uploads of data. This capability is provided using the Diagnostic Tracking Service and is complete opt-in.

     • Mike thank you. Having tried all of the above, I found your comment. Seems this caused my problem too. Service stopped - now to look at whether there will be any negative impact from stopping the service.

     • Hi Mike - thanks for that - mine was similar but not the same. 'Connected user experiences and telemetry' for me.. I guess they were aiming for a bad user experience in this case!

       Hope it helps someone.

158. I have tried all these fixes and some others and disk is still maxing out.

159. It was Flash indeed, thaks.

160. This was a huge help. Killing the flash plug in seemed to do it. Thanks so much for giving me my computer back.

161. Ive done all the supposed fixes to my Acer Aspire from last year and still 100% disk usage. I rarely use this computer anymore but it's my only computer with dedicated graphics so I want to revive it. Will I have to bring it to a repair shop?

162. For me, disabling Adobe Flash Player solved the issue. Disk usage dropped from 100% down to the regular 0-5 % when ideling.

163. Thanks bro, it fix my problem, adobe flash was the cause.

164. Thank you for the easy to follow steps! It fixed the issue on my PC, it was the Search Indexing that had been using up my Disk resources.

165. I have solved the issue with my computer and Windows 10 100% disk usage. I was troubleshooting the IDE controller driver and ended up running Troubleshooting from control panel. I chose hardware and sound and then chose hardware and devices and let it run. It actually came back and suggested to set the IDE controller to use Windows 8 compatibility. It's been 3 days and have had no issues. I can actually open up 20+ tabs in Chrome with no issues (catching up on updates in face book).
     I tried all the other registry changes, app disabling, etc. etc. posted and nothing helped. Uninstalled anti-virus, disabled auto updates downloads, you name it, nothing. This has been a stable change so far.
     Hope this helps someone out there that was getting as disgusted as I was :)

166. It's not working , It's still showing 100 % usage of disk space

167. I tried each one of these remedies in successive order with reboots as prescribed.. I'm not sure if they all worked together but after executing the last one I finally saw the disk usage drop and now fluctuates up and down.. no longer stuck at 100% or reaches beyond 99%.. I'm relieved for now.. Thank you

168. I have tried everything in this article and several other things in various other articles and youtube videos I have found. I just reinstalled the operating system (completely fresh - didn't carry over my apps or my files) and every since I got it back up and running it has been running at 100% disk usage. I don't know what to do. Its a Dell XPS machine with 16gb ram. Its way over-powered for what I use it for - it shouldn't be running this bad. Someone please help!

     • One thing to watch is not to measure your disk usage for a bit after restart - it can take a few minutes for necessary startup processes to settle down, so implement these suggestions - especially I found 'superfetch', and 'windows search', and disabling things like adobe updater, and other automated update services.

       If you work at it, you can definitely reduce your disk usage.

       But once again I must rant, 'how could something like this get out the door? I'm definitely a fan of windows, and I love windows 10, but this is nonsense'. Hopefully an update comes along to address some of this at least!

169. Hi,
     I have a new laptop Lenovo Thinkpad E450. I have Windows 10 installed. The laptop was working fine in the first one month but now it has started hanging quite a bit. When I checked the task manager, the disk usage kept showing at 100% with absolutely no processes running. I have tried all the checks and directions listed in this article but it hasn't seemed to help. Can you please help debug the problem.

     • I have a Lenovo Y700 and have the same problem. Usually mine is either the System or Antimalware service that is highlighted as the most usage. Any help is appreciated

170. I've tried everything on the Internet and I still can't get my disk to stay low for more than 5 minutes. It goes down to around 5 and then shoots back up to 100 every time. I just bought a new hard drive so I know that's not the issue. Please help.

171. Now my disk usage sits at ZERO PERCENT unless I am actually doing something!

     It's almost creepy to have my machine so quiet these days, the moment I pause in my work..

     I'm a bit dismayed about this kind of quality in Windows 10 - which I really like - but stuff like this kind of gets to you.

172. Thanks so much for this excellent info.

     After taking most of these recommendations, it also occurred to me that UNchecking 'Compress this drive to save space' on my C drive properties (which launched a looong process in itself) is also a likely culprit.. I would think this feature (which is enabled by default) could cause Windows to continually comb your drive for wasted space. Anyhow, after all of these measures my usage has gone down from a continual 85% or more usage, to somewhere between 5% to 7%.

     Both myself and my hard drive thank you profusely!

173. Thanks for your help. For me it was the Adobe Flash Player in Chrome browser. As soon as I Disabled that plugin I could see that the Disk usage had gone down from 100% to about 10/20% average.

174. Wonderfull summary.
     Windows Search does the trick for me.
     But.. I love the feature / the concept of indexing, which allows me to find anything on my PC quickly.
     So, if I disable it - wouldn't I lose the 'search' ability ???
     Isn't there a way to fix the bug which causes the loop?

     Thanks for your help!

175. Here is the Microsoft recommended solution:
     https://support.microsoft.com/en-us/kb/3083595

     and it worked for me :-)

176. I have been having problems with my Inspiron 15 ever since I started using Adobe Creative Cloud and the associated Adobe products. Before this it worked fine. Now I am having the 100% disc usage problem and none of the steps, tricks, or tips I've found so far have helped. Is my problem stemming from the use or presence of the Adobe products? If so this may explain why the tips that help others aren't helping me.

177. I tried all the options and didn't help me, I read on a forum that changing the battery plan from 'balanced' to 'high performance' may be the answer, for me it was! suddenly the problem was solve :)

178. I tried all of these fixes and it's still %100 disk PLEASE HELP

     • Try changing your battery plan from balanced to high performance (in case you're using a laptop).

179. It's really helpful. The 2. tip was works really well for me. My pc was at 100% disk useage 2 minutes ago, now its 0-3%.
     Thank you for this help informations. God bless you.

180. Once I stopped superfetch service my disk usage was down to 2 percent. Thank you so much :)

181. WOW .. YES! *arm-pump* I stopped the Windows search and disc went back down to 1%
     Thank you!!

182. I Googled on how to get rid of bloatware. I got your page. Your mistake is putting every bit of knowledge you have on one page, which totally confuses or hides the main issue for most users, thus rendering your page useless.

     You should use link for every item you want to write about. Then, the user needs only to go thru the list of links, find which one they need and click on it.

     By the way, I never did find an easy answer to deleting bloatware on this page.

183. Got my usage down form 100% to about 2% by the following:

     using a free antivirus instead of Windows Defender
     following the three steps above. Biggest change was disabling flash in google chrome.

184. Thanks, disabling Windows search did the trick, was a bit worried that my poor HD was going to wear out!

185. Thank you so much! I do not usually comment but this time I thought I must. My brand new Asus computer has been probably the slowest computer that I ever had. The disc usage has been at 100% all the time. I did what I know, stopped lots of startup programs, and canceled background tasks, but it was still at a 100%. I tried every scan, expecting to have a virus, but apart from a couple tracking cookies, nothing came up.

     After I disabled Windows Search, that alone decreased my usage to 75%-80%. The difference was amazingly noticeable. Then I did the next thing, disable the superfetch. Unbelievably, my disk usage went down to 5%-25%. I can finally use my brand new computer. Thank you so much!

     I wish there was some way to spread this article. Personally, I didn't think that 100% disc usage was a problem, until I just started to google like crazy. I'm sure that there are a lot of poor souls that are struggling with this issue, and your article saves lives of all computers that are close to be thrown out the window.

186. WOW !! It was the chrome plug-ins. I disabled Flash and 2 other plug-ins and my disk usage immediately went from 100% to 4%. YTB (You're the best).

187. I am curious, how common is this issue? Also how damaging is it to the pc to not fix the issue?

188. Thank you for the insight. My AVG found one threat which load my disk usage down quite a bit, and then I did the others as instructed. Now I'm under 1 Megabyte a second on my disk .

189. A different trick helped me out - one from Microsoft: https://support.microsoft.com/en-us/kb/3083595.

190. omg thank you so much disabling flash seemed to do the trick. I unistalled flash and disabled it from all my web browsers and now it seems to be fine although if i open multiple things like steam and google and microsoft edge the disk usage can go to 60% for sometime it quickly goes down again to like 10 or 15 so thank you very much..

191. I love you for this thread, had this problem for weeks, finally fixed it!

192. Check disk worked. I have been fighting with a slow computer, typing and waiting 3 seconds for it to appear on the screen, and scrolling that works in jerks and spurts. Went through each step and it did not work until I did the Windows 10 CHKDSK through the C: admin prompt. I even restored my computer to factory settings once and it was still slow and sputtering. Only your solutions worked. Thank you so much.

     I was wondering if after removing Flash, if you had to reboot the computer for it to take effect. If you do, that may have been the problem too. I didn't reboot the computer for any of the above fixes until I entered the CHKDSK command.

193. If possible change power supply. And check effect.

194. I did all of the steps and the disk is still at 100% usage. What should my next step be?

195. Disabling flash player resolved the issue. Thanks!

196. Disabling the flash plugin on chrome fixed the issue.

     Thank you

197. Isn't there a fix that doesn't limit my user experience?

     1. I always use search to find everything, i don't want to disable the only useful thing that wasn't prevalent in windows XP

     2. I need superfetch working since there's a memory stick readyboosting for extra RAM, from what i know it uses superfetch. It really impacts my performance without readyboost. And i can't install more RAM internally since it would cost a lot more and i'd have to remove the disk drive.

     3. Why hasn't windows made a fix for this, my hard drive already crashed once, if it breaks i'm going to sue.

198. my PC was running at 99% CPU use and a couple of things here dropped it back to 4%.

     Plus I found a bunch of Google Chrome extensions that i never use in the process of following this article.

     But I am still unsure what Command Prompt (Admin) does. I followed the steps above to disable it but do not know how to enable it. Do I need it?

     I am not even sure what it is. I read the article above under 'read more' but I can't say I much clearer. Can anyone tell me in a few words;
     1. what it does? 2. Do i need it? and if then 3. How do I re-enable it?
     Thank you

199. when I type net.exe and enter, there is a small popup which flashes and disappears!!! help

200. After several months of research I found this blog post.
     The remedy was net.exe stop superfetch.

     Instantly dropped the Disk usage from 96% to 2-3%.

     Thank you very much.

201. Oh my good. Thank you so, so much! You have no idea how happy I am right now. Thank you!! <3

202. Dear Christian,

     Your page is the BEST. I've tried everything you mentioned and it only worked for me when disabling Flash in Chrome. Good job, Thank you so much :o)

203. Disabling Windows Search and superfetch worked for me. Thank you so much!

204. This is the 3rd fix I have tried this week, disabling Adobe in Chrome being the latest. My question is, how do I watch things in chrome (like live feeds) that require adobe?

205. net.exe stop superfetch it wont access to my laptop asus core i5

206. i am windows 10 on latest i5 laptop my laptop gets slow down due to 100% hdd usage then i came at you article and disabled Windows Search and Superfetch Service now my it working very fast and hdd usage 2%.
     thank you

207. Oh, and I can't even get services.exe to open.

     • Services.msc

208. This has been happening to my computer for months now, and none of the tricks I've found on the internet help. I guess it's time to buy a new computer.. :(

209. Disabling Windows Search worked for me, disk usage dropped from 100% to 3%.

     thanks for the tip.

210. This was definiately Flash Player for me. Brand new ssd and fresh win 10 install. Didnt have this issue at my office with the same situation, but I also use Chrome Canary there.

211. Update to my previous comment. Since none of the suggestions worked, I fired up services.msc and went through disabling every running service. Windows Update was the culprit. It wouldn't stop, but disabling it and restarting the computer solved the problem.

212. Wish I could say it worked. Absolutely no change. The disk activity light flashes constantly. I'll keep looking for a solution, since the computer is almost useless.

213. This article has helped me solve my slow PC. Problem was due to Windows search services. Disabled it and the problem is solved.

214. I have an Asus laptop, 8GB ram, updated to Windows 10 shortly after purchase. No problems for a long time, but recently started running slow and I noticed the high disk usage before finding this page.

     I tried several things suggested here: Disabled superfetch, windows tips, windows search, and completely uninstalled adobe flash playe, (even though I need it for a streaming app I use, just to see if this was the cause). Also changed the pagefile settings as suggested by Devin, 22 Apr, 2016. I also did the Optimize drives suggested by Connor Worth 28 May, 2016. Nothing seemed to work. I had the Optimize Drives window open and it was going through multiple passes of defragmenting on the C: drive without stopping even after a couple hours while looking at other possibilities, so I decided to try stopping this and turned off the 'Scheduled optimization.' As soon as I did this, the disk usage dropped from 100 to 4%. I am wondering if the defrag/optimize was running in the background and this was causing the whole issue. If nothing else works, look at all the defrag and optimize suggestions and try disabling everything that is related to this. BTW, the process that showed up as the main disk user 'System and compressed memory.' Hope this will help someone.

     • This was my exact issue. I tried everything. Finally, I waited till my laptop loaded up which took around 45 minutes and a couple of restarts (brand new) then I opened the C drive -- each click/action took a couple of minutes to execute due to lag -- finally I right clicked the C drive>> tools >> optimize, I stopped the optimization and immediately my disk usage went from 100% to 0% - 4% range. Naturally if I'm doing some other task it'll jump up but then come right back down. I also turned off automatic optimization to prevent this in the future. Finally I enabled my extensions and superfetch as well as Windows search and anything else I disabled before I found this solution. Now my laptop is running smoother than ever!! Man, thank you so much!!!!

215. Yap it was the Chrome Adobe Flash Plugin Thanks for your help :)

216. In a previous posting here (5 July 2016) I reported that I had tried everything described in the main article and the comments but no solution worked. I looked again at the numbers in the task manager panel and saw that Norton Internet Security showed high disc activity as well as:
     Service Host: Local System
     Service Host: Local System (Network Restricted)
     System and compressed memory.

     So I uninstalled Norton and all is well with the disc again. Clearly something was wrong with NIS.
     For the time being I'm relying on Windows Defender for my internet security but I may try re-installing Norton some time soon to see what happens.
     So to anyone else who has tried everything here I suggest you also look at your internet security application.

     • @Blankenburg THANK YOU! I tried everything on the list too and nothing worked. But I had an old expired norton program along with all that extra crap that came with it and I uninstalled it (it took like 3 hours..) but as soon as I did disk usage shot down to 5%. Never would have suspected a single program. Thanks again

217. Settings>System>Notifications & actions. Set 'Show me tips about Windows' to OFF. Disk usage plummets on every Windows 10 rig I've done this on.

     • None of the above steps worked. I did what you suggested and it dropped to 10% from 98-100%. Thank you so much

     • Wow, this worked for me when nothing else had..GREAT WORK!

     • You're a God. This was it!!!!!!!!!!!!!!

218. Ironically, this website caused my CPU usage to hit 100%. Installing AdBlock fixed THAT problem, but I am still getting the 100% disk usage issue.. it mainly occurs when using Windows Explorer..

219. Not sure which one fixed the problem for me but my PC is running fine now. Only thing bothering me is disk usage is still hovering around 90-100%

220. Prior to reading the above I have tested the hardware in my laptop with various software without finding fault.

     All of the above have also not made any difference - the hdd still runs at 100% all of the time.

     Any further suggestions help would be greatly apprecaited.

     Don

221. Everything worked a bit, but the big culprit for me was:
     Adobe Flash in chrome. Disabled, now its down to 10%

222. I have a Lenovo PC that has run reasonably well since I purchased it in 2013. I regretted upgrading to Windows 10, but it hasn't been that bad. However, in the last few months I've noticed a slow down in performance. In the last few days it worsened significantly to the point where nothing really worked anymore. I did some research and found the Microsoft support article at https://support.microsoft.com/en-us/kb/3083595. I followed the instructions carefully but it did not help. I then found your article and followed all the instructions carefully. Still 100%. Then a found another article that suggested disabling superfetch through services.msc instead of through the command prompt. Voila. Instant relief. It's not perfect, and it still often shows 100%, but it seems to have gotten my computer back to the point where I can actually use it. I've ordered a major RAM upgrade to help.

223. My disc usage is still at 98-100% the following steps only reduced it by a bit :/

     • if any of you guys have windows 10 go to settings and system >notifications+actions then switch off 'Show me tips about windows' if you haven't already it should help.

224. After the Anniversery Update of Windows 10 Disk Usage went to 100% and bogged me down matey! It was superfetch causing the problem. Disabling Superfetch brought Disk USage down to the teens ranging up to the 30's but no more problems.

225. Disk usage went from 100% down to 7%. Super helpful

226. New Adobe Reader uses 100% when open.
     If you turn of caching of PDF documents it solves the problem.

     • Dude, thanks a lot !!!!!

       tried all of the solutions, even everything what was written in comments above yours, and only when I went to chrome://plugins/ and turned off Chrome PDF Viewer my disc usage went to 4%.

       thanks a lot !!!!!!!

       • I tried all other suggestions (in article and all other comments above), nothing worked.

         Scarface music free download. Disabled Chrome PDF Viewer, and 2 seconds later I am rocking at 1-4%. Oh sweet jebus, thanks!

227. I have a brand new Toshiba Satellite L55w, 100%disk usage, only 6 months old. Doing it from the start. Tried everything here, still 100%, any help? Most appreciated, Michael

     • Toshiba you say! Kill every piece of Toshiba software you can 1 by 1.
       I've worked on a number of Toshibas and have seen this a number of times, even Gigabyte has done this. Or if you wan't kill all of their software just to see if it is any one of them causing the problem.

228. It wasn't Flash in Chrome that was the issue but Flash in Firefox. Once I deactivated that CPU on one of my disks when to normal.

229. After disable the adobe flash my laptop speed up really good.only thing worrying me my disk still shows %100.when the window pops up it takeshalf a second to jump from %1 to %100.

230. It's a lot easier to understand the disk usage column (on the Processes tab in the Task Manager) if you change the values to percentages. Right click the name of any process > Resource Values > Disk > percentages.

231. The flash lugin from Chrome was my thing. Worked like a charm. Thanks !

232. I have tried everything in this article and the comments, and the only thing that seems to make it any better is stopping any running tasks in the tasks scheduler, but it still only goes down to 45-50% and then it eventually goes back up to 99%. I have a Dell Inspiron that is 1.5 years old. I had this problem in Windows 8, but it got worse when I moved to Windows 10 earlier this week. Any ideas?

     • I also disabled the native client plugin on chrome, which appears to have fixed my problem. Hopefully that doesn't mess something else up.

       • Yep disabling the native plugin worked a charm, thanks CJ.

233. Was [bleeping] Flash for me. That's what finally broke the 100% CPU. It had been pinned to the ceiling for 10 mins or more until I killed Flash.

234. You are a GENIUS. disabling the windows search thing has completely sorted my laptop out. THANK YOU.

235. none of these fixes work please help.

     • i know how you feel bro :(

       • I think i found a fix follow these steps:

         press the windows key and search for this: Task Scheduler

         and then open its going to take few moments or minutes to open

         Then go like this:

         Task Scheduler Library/ Microsoft / Windows / then look for a file named: Defrag

         Tap on it

         wait few moments

         Look at the right their going to be one task which is one line...

         then tap on it

         after that right click on it

         then click disable

         That did it for me hope it works for you, if that didn't work check the whole hardware of the computer or laptop.

         - Abd

       • just to add something if there is more than one task in the Defrag folder also disable them

       • also do this too

         search in windows for: Services and look for superfetch and right click on it then click proprieties then click on startup type and put it to disabled
         then click stop then click ok and do the same for windows search.

236. I followed your steps and it kinda took care of it but it is still spiking at 100%..it goes down to 0% for a brief period and then climbs quickly again to 100% for a short time and then repeats..any ideas?

237. Thanks very helpful D:)

238. thank you

239. To fix this bug, you need to go to Settings > System > Notifications & actions, and disable all notifications. It should work..

240. Tried everything suggested here. No improvement. (Haven't done chkdsk as I don't think it would finish with the heavy load on disk and CPU.)

     What I see is high numbers on Service Host: Local System and on System and compressed memory. This starts as soon as system boots.

     Any other ideas? Anyone?

241. so far so good I tried one and it worked like magic thanks but on the other computer nothing is happening

242. I did every step. Disk is still pegged at 100% and PC is slow. Any other ideas?

243. Must be the government spying

244. So I tried to do the disk scan and repair and it has been stuck at 10% for an hour now. What would be my next course of action?

245. But all these disk processes are mainly getting high due to that 'system and compressed memory' thing i have so observed..if that can be somehow lowered that would do most of the trick.

246. System error 5 has occured.
     Access is denied.
     it keeps showing up after i do the command prompt thing for superfetch and for windows search.
     Any suggestions?

247. The windows search thingy worked for me.
     thanks

248. Le Sigh..
     I have windows 10 (64 bit). Nothing running except a web browser (google chrome or Firefox doesn't matter). I open one program (On1 to view photos) and it goes to 100%disk and stays there forever..Skype can take five minutes to open. The whole system was through diagnosis at the shop and everything came up fine. WTH is wrong? Superfetch is off. Windows tips off. Windows search (I believe is off). It is an XPS 8500, still a fairly strong machine..

249. After the Windows search and superfetch it dropped from 100% to 2% and is not going past 10%, thank you so much!

250. There's only ONE solution that works perfectly.

     Go to Settings, System, Notifications, and turn off 'show me tips about Windows.' (all of them besides the app notifications).

     You won't believe your eyes with the immediate improvement. Some PCs even dropped from 100% to 2% of disk usage.

251. did the cmd prompt 'net.exe stop “Windows search”'. Usage dropped from 99-100% to 1 % in about 15 seconds. Need to try a more permanent fix.

252. Stopping superfetch was key to dropping disk usage from ~100% to ~7% on a 3yr old HP G72 machine which was recently upgraded to Windows 10.

     Thanks for pointing this out! rgds, Tim

253. Service Host is making high usage disk at my PC on Win10

254. Go to control panel/ system and security / look under administrative tools click free up disk space after that go to Defragment and optimize your drivers

255. Hi, running windows 10 and super fetch is nightmare causing 100 pc disk usage. Turn it off and disk usage dropped way down. Suspect it's adobe premiere pro interaction with it? Is that plausible?
     Thanks

256. OK Great article and the comments were just as helpful! I have a Hewlett Packard Phenom PC (2010) with Phenom II X6 1045T Processor (HPE_410Y).

     Was up to 100% disk usage. Noticed first of all I've had to stop using Firefox (that was a while back before the disk usage went so high).

     So what worked for me from this article - already using Malwarebytes so that wasn't the issue. I did all 4 steps in the article but the chkdsk kept bumming out at the 13% mark. No luck switching off Flash, but PauliePepperoni's comment about switching off Update Notifications to 'Notify to Schedule' did it.

     Got a lot of nerdy satisfaction out of seeing that Command Prompt, again. It's been too long.

257. I started having this problem at the beginning of January after I made an update. I had the os(8.1) instaled for more than an year and never had this problem. After a few months of trying all sorts of solutions I found on the boards, and two formats I noticed after the 2nd format that after I installed 'Microsoft Visual C++ 20XX Redistribute' the disk spiked to 100%. Apparently it's a driver conflict.

258. Thanks!! :D

259. Hi All,
     Please try this, I had this issue and it seems some others encountered the bug. What fixed it for me is going to settings, system, notifications, and turning off 'show me tips about Windows.' I believe that was the one causing problems, though I turned all of them off besides the app notifications. System processes went back down after a restart and haven't spiked since. I guarantee 100 %

     Thanks
     Shabari

260. This totally worked for me: disable 'superfetch'

     Before disk usage always ended up 100%, froze the computer, very frustrating. Problem solved.

261. Thanks Devin. It works so fine. I was seriously thinking their is some problem with my hard disk.

262. Ive noticed that the backround information transfer service gets re-enabled after a few seconds. If you go to Settings: Updates and Security: Windows Update : Advanced options and switch it to 'notify to schedule' that seems to keep it disabled.

263. I tried what you said, it went to 2-3% of disk usage then it peaked at 100%, help please

264. Nothing has worked. Nothing. I've been looking for a solution for weeks now, and my disk usage still going nuts. This is a very fresh laptop, Core i7 with GTX 980m, Windows 10, got it last year. I don't know why the heck this is happening. I tell you this though, the huge disk usage mostly happens while I'm watching youtube videos. It doesn't matter which browser, whether it's chrome, IE, or edge, youtube spikes 100% disk usage like heck and everything becomes slow-mo. I need serious help.

265. After trying stopping and disabling Windows Search, superfetch and Flash my disc usage only stopped be showing 100% temporarily. What really fixed it was changing the pagefile settings. Go to Control PanelAll Control Panel ItemsSystem then click Advanced System Settings on the left. Go to the Advanced tab and click settings under performance. Go to the advanced setting in the Performance options panel. Hit Change under virtual memory and then uncheck Automatically manage paging file size for all drives and choose custom size instead. Set Initial size to 1024 multiplied your ram to convert to MB and set max to twice the Initial.
     Ex. for 8GB Ram: Initial size at 8192 and Max at 16384.
     Hit apply and OK and then restart your computer. Stopped my 100% disk usage and windows now loads faster hope this helps.

     • Thank you so much for sharing this indeed Devin. For me too using the article solutions made the problem subside a bit, but it would hit red (100%) like every 2-4 minutes. I manually set my pagefile settings to 4096-8192 (since I have 4gb ram) and the problem disappeared. No more Windows getting stuck, no more bottlenecking and everything works great.

       It definitely helped. Thanks Christian for trying to help and thank you Devin for sharing your findings and helping me with my problem :)

       • OMG, dude thanks so much, it definitely help my issues.

266. Thanks a lot ! ;D Never could have thought the adobe would give me 100% thx thx thx ! : }}} <3

267. This is a problem for me that keeps cropping up. First, I disabled “show me tips about Windows' as Kris suggested. That solved the problem. Or so I thought. About two weeks later, my system slows down again and I notice that the HDD is running at 100% again. Then I did what you said Christian. I turned off Windows Search (temporarily for now). That seemed to immediately help. But for good measure, I also disabled Flash player in Chrome, even though I almost never use the Chrome browser. So all is good now and we'll see what happens after reboot. If the problem starts again, I'll shut off the search service (maybe permanently).

     As part of this most recent episode, I had a more sinister problem with a program called Java Web Start Launcher. It was running multiple times; too many times to even count. I did some research on this but found nothing that was within my ability to solve. So I did a system restore. That got rid of the multiple Java Web Start Launcher programs running, but my disc use was still at 100%.

     Christopher, maybe you know something about this Java issue?? This was not the first time I've had this problem with this program.

268. That seems to have solved my problem of the disk running at 100% all the time - thanks.

     But I couldn't get chkdsk to work - it kept stalling at 17%. Eventually I had to abort it to get the laptop to restart.

     Should I be worried?

269. Turned off superfetch and notifications. Disk was still at 100%. Then my computer went to sleep from inactivity, came back and disk was at 0%!

270. I updated from windows 8.something to 10 and idk if the problem was after I switched my default browser to chrome or before but I quickly noticed the slow performance and checked task manager and saw I was maxing out the disk at 100% so I found this article, first thing I tried from the list was the google chrome adobe flash thing and it immediately dropped my disk usage when I disabled it so I would suggest trying that first if you had a similar situation.

     Thanks for the help!

271. I had this issue and it seems some others encountered the bug. What fixed it for me is going to settings, system, notifications, and turning off 'show me tips about Windows.' I believe that was the one causing problems, though I turned all of them off besides the app notifications. System processes went back down after a restart and haven't spiked since.

272. I have done all of these and I still get around 100% and things running at the top are only using about 0.2 mb/s or so why??

273. Please update java and you should be oke .

274. So this is the second time I've had this issue. The first time it got so bad the only option was to refresh the computer and loose all my programs. That helped for about a month and now it's slowing down again and showing 100% usage. My computer is a dell 15R laptop bought in 2013 and update to Windows 10 summer of 2015.

     I've attempted all suggestions on this page and switched off all windows notifications and disk usage remains at 100%

275. This is a great set of advices.

276. Hi. None of these made much difference for me, But what did work was switching off 'Windows Notifications' via System Settings. Disk Usage dropped from 100% to 2%!

277. Issue resolved. Cheers

278. I did every step and nothing worked. Still at 100% and I have had this computer less then a year! Beyond frustrated!!

279. I was trying hard since few days nd finally Superfetch was the bug, thanks bro

280. I disabled Adobe flash and my processor and disk went from 99% to 30-40%

281. My service manager won't open. I'm not getting an error message, just nothing happens.

     • Man go to this location and open services as admin

       C:ProgramDataMicrosoftWindowsStart MenuProgramsAdministrative Tools

282. Why would i buy new Windows to turn off all of theese shit to Make it work normal ? Dont see The poinn. Windows 7 rules

283. deleted defrag in task scheduler and back to normal! thanks so much!

284. Turned off Flash and finaly dropped majorly! ..and as I am writng this it seems it only fixed it for a few minutes. Back to a 100! What do I do?

     • Go to Settings > System > Notification and disable tips about Windows.

285. My Dell Windows 10 was running at 100% and I was worried. I went through the list doing every one of these and still nothing. When I tried the last one, disabling the defrag, it dropped to 8%!!! Thank you so much!!

286. OH no it just went to 100% again..only for a few minutes..mmm anyway still a vast improvement.

287. Super Happy with this advice was at 99%-100% ALL the time on my 1 yr old lappy. i got rid of an expired Norton, didn't change .. Turned off windows search and wallah..1%- 3%. it's confusing why Windows allows such a stupid situation.
     NB service.exe didn't work for me however services.msc did??
     Thanks for saving my laptop from a violent death.

288. I'm using Windows 10 on a Gateway laptop. I disabled superfetch and the problem was solved! thank you so much!

289. Hmm. I tried everything on the internet. But my problem is a little different.

     First, when I open my laptop, everything is fine. But if I connect to wifi, it suddenly reaches 100%. I also did a full scan. Deleted threads. Checked drivers, last verison. But still have the problem :(

     • Found another article online from Microsoft. Not really sure what it all means (kinda new to the laptop scene) but may as well give it a go.

290. Awesome piece! Disk usage dropped from 99% to 17%.

     Keep up the good work!

291. Thank you!!! Disabled flash and disk usage came down to 3 percent.

292. I was struggling with this for a long long time. When I disabled Flash it worked like a charm. Thank you very much.

293. After disabling prefetch my 100% went to 3% immediately.. THANK YOU!!!

294. Thank you!!! u really helped me !

295. Hi, I tried everything above but I still have disk usage 100% I do not know what to do

     • Something that worked for me was to go to settings, system, notifications, and turning off 'show me tips about Windows.' It lowered my disc use from 100% to 4%. Give it a go and see if it works!

296. THANK YOU! Thank you! Thank you! I disabled both Windows Search and superfetch. Disk usage went from 100% & is currently at 0%.
     This is my work & school computer, & I was freaking out a bit when i couldn't get anything to run properly. There aren't enough words to express my gratitude!

297. Open task manager >select google chrome >hit end task
     This worked for me, be patient it will take some time.

298. Thanks, Disabling Adobe Flash player did the good job till.

299. Disabling Adobe Flash player did the trick. Reduced Disk usage from 100% to 9 %!!!
     Thank you for this tip. Very useful!

300. useful article, thanks for your effort. the problem has been solved for me when I stopped 'adobe flash player' from Google Chrome
     you deserve 5 stars

301. Only disabling XX (superfetch) solved the problem
     Disk usage reduced from 100% to 11%.

302. Do yourself a favour, and save your sanity. Ditch Windows...and move to Linux. No more Windows Search, no more defrag, you can easily decide what YOU want to start at boot time. And NO chance of all that crap MicroSoft are dishing out to Win 10 users!

     • Yes, no more Office products either. I'm sure the boss won't fire the secretary at all for formatting the company Lync enabled reception desktop that can no longer receive calls or edit the company Outlook calendars. And Linux doesn't eliminate defragging.

303. i just brought a new hdd and installed new win 8.1 all drivers are upto date used 3 driver update software to check all drivers. all are upto date and have run multiple times antivirus software for any infection. but nothing seems to solve the high disk usage. problem is the disk usage shows as 100% with a transfer speed ranging 0.1MB/s to 1MB/s highlighted in red with such a less amount of transfer speed. this happens only with system and service host:local service process. after sometime things get normal. what would be the problem any suggestions would be helpful. thank you in advance.

     • Install DoNotSpy for windows and it will disable all that crazy stuff WINDOWS is throwing at your disk and man you will be free this is how I saved my pc.. cheers!

304. 'you’re using a brand new Windows 8.x or Windows 10 device, you’ve only had it a few days. '
     You may be using brand new hardware but you are also using an O/S that has not had a major rewrite since Win NT came out. You are using an O/S that by default starts all available services, many of them unnecessary, at bootup time.
