Reset Virtual Memory in Windows 10
Virtual memory uses your disk as RAM. When your computer runs out of RAM, it will use your system drive to store files temporarily and will swap those files back when required. Therefore, it can be considered as the physical memory despite the fact that the performance can’t be the same.
However, if something goes wrong with the pagefile.sys, it can cause 100% disk usage issue on your Windows 10 computer. That’s the reason why you need to reset/reconfigure virtual memory settings to make sure everything is fine.
- Right-click on this PC and choose Properties.
- In the System window, look at the left sidebar and click on “Advanced system settings“.
- From the Performance section, click Settings.
- Then select the Advanced tab, and click on the “Change” button.
- Make sure the box named “Automatically manage paging file size for all drives” is checked.
Tip: To verify whether the virtual memory is the cause of Windows 10 100% disk usage problem or not, you can uncheck the box (mentioned above), choose “No paging file” and press OK. After that, reboot your computer to see the result.
Remove Windows Temporary Files
I would strongly recommend you remove all temporary files and then reboot your Windows computer. According to a few suggestions from users on the Microsoft forum, cleaning up all Windows temporary files will help to resolve 100% disk usage issues in Windows 10.
- To do so, press Windows + R, type temp and press Enter.

Windows 10 creates Prefetch files every time you run applications on your computer. The purpose of Prefetch files is to record information about the files loaded by the applications, so as improve the loading times of applications by making use of the recorded information. Again, this feature has been linked to 100% Disk Usage Error in Windows 10 and you may want to disable this service by following these steps.
Type Regedit in Windows 10 search box and then click on the suggested regedit. Once the registry editor is open, navigate to the following key.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
