Solution 1 – Run DISM

If your PC is malware-free but you’re still stuck with the same error, we suggest running DISM alongside the System File Checker utility. The Deployment Image Servicing and Management tool should fix all system corruption with rather ease.

Here’s how to run DISM along SFC via the elevated Command Prompt:

  1. Open Command Prompt as an administrator.
  2. In the command-line, type sfc/scannow and press Enter.
  3. After its done, type the following command and press Enter after each:
    • dism /online /cleanup-image /checkhealth
    • dism /online /cleanup-image /restorehealth
  4. Reboot your PC when everything ends.

Solution 2 – Reset your PC to factory settings

Finally, if you see negative results once again and there are signs of system issues, we suggest resetting your PC to factory settings and moving from there. This operation will indeed relieve you of all installed applications, but you at least get to keep your files.

Here’s how to reset your PC to factory values on Windows 10:

  1. Press Windows key + I to open the Settings app.
  2. Choose Update & Security section.
