SFC

  • This tool will immediately start scanning the whole PC for corrupted files and repair them. 
  • Usually, this takes 15-20 minutes, however, this might increase depending on the level of corruption inside your PC. 
  • After the scanning/repairing process completes, restart Windows 10. 

Check if the error resolves from the next logon or not. 

3] Check and Resolve Corrupted Windows Image

At times, a corrupted Windows Image may also prevent your PC from getting updates. So, you must check and ensure there isn’t any corruption on the operating system itself using DISM. To run this utility program, use these steps –

  • Make a right-click on the Windows icon and select Run.
  • Type “cmd”, and press Ctrl + Shift + Enter simultaneously to start Command Prompt as an administrator.
  • When UAC prompts, hit Yes.
  • On the elevated console, execute the below codes one by one. The first two codes will scan for issues on the computer, while the third one will restore PC health (if possible). 

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth
