  3. Again on new window Go to the Advanced tab, and choose Change… in the Virtual memory section.
  4. select Advanced tab, and click on the “Change” button.
  5. Make sure the box named “Automatically manage paging file size for all drives” is checked.

Note: 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, rebooting your computer to see the result.
