I have broken this into , followed by the plain text version for a forum post, and a script outline for a video.

  1. Open Command Prompt as Administrator.
  2. Run DISM /Online /Cleanup-Image /RestoreHealth (press Enter).
  3. After that completes, run sfc /scannow.
  4. Wait for both scans to finish. If they repair files, reboot.
  1. Run a full scan with your antivirus software to detect and remove any malware.
