Once the SFC scan is finished, check if the problem is still there. If the issue is still there, or if you couldn’t run an SFC scan, your next step would be to use a DISM scan instead. To do that, just follow these steps:

  1. Start Command Prompt as an administrator.
  2. Now enter Dism /Online /Cleanup-Image /RestoreHealth command and run it.
