4. Type CMD
C. Type the following commands at the CMD Prompt, Enter:
dism /online /cleanup-image /restorehealth ( Make sure a space is between each / after the last command word.)
{and at the blincking cursor, wait...(go to lunch time) for completion message...}

Then upon that completion, at the Command Prompt, type in:
sfc /scannow
{Enter, and wait...for completion message...}
If dism and sfc both completed and show no remaining issues, run these commands:
