Your computer may be infected with malware that causes your disk usage to spike. If you have anti-virus software running in the background, then it has caught the problem.

Method 4: Disable Windows Search

A known bug in Windows 8 and 10 could cause a search loop, which could be the cause of your high disk usage. To temporarily stop the Windows Search utility and see if it improves your disk problem, open the admin prompt, and enter the command: net.exe stop “Windows search”. This will prevent Windows search from running until Windows is restarted next time.

If the determination that Windows Search responsible for your Windows 10 disk usage reaches 100%, you can disable it permanently by following this procedure:

  1. Press Windows key + R, type services.msc, and hit Enter.


  2. The Services window will open. Select the Windows Search item and double-click on it to update its properties.
  3. Select Disabled under Startup and OK to save your changes.

Another feature of Windows 10 that can cause the problem is the Windows Superfetch service. You can temporarily disable this service in a similar way to Windows search with the command: net.exe stop superfetch

To disable the service permanently, use the same procedure as to disable Windows search.

  1. Go to Start> Control Panel> Hardware and Sound> Power Options> Change plan settings> Change advanced power settings.

Another step to take when investigating the cause behind your Windows 10 Disk 100% usage issue is to disable your antivirus software temporarily. See if this improves your disk usage. If so, you may want to consider changing anti-virus packages. Even Windows Defender can cause problems by increasing I / O, and network usage can lead to high disk usage.

Virtual memory treats your disk as if it were RAM and uses it to swap temporary files when the actual RAM runs out. Error in the pagefile.sys can cause 100% disk usage on your Windows 10 machine. The workaround is to reset your virtual memory settings.

  1. In the ” System Properties ” of your computer, you need to click on ” Advanced system settings “.
