Return to the administrator Command Prompt and run:

net start bits net start wuauserv

Restart your computer and check for updates again.

Important: Stop the services before clearing the cache. If a command reports an error, review the message rather than assuming the operation succeeded.

DISM /Online /Cleanup-Image /RestoreHealth
