    net stop bits
    net stop wuauserv
    net stop appidsvc
    net stop cryptsvc
    net stop msiserver

    This stops Windows Update, Application Identity, Windows Installer, and Cryptographic Services temporarily.

  3. Open File Explorer and navigate to the following folder:
  4. Select all items in that folder and delete them. However, as a general rule, it’s advised to delete only files that are older than 10 days in that folder.
  5. Switch to the Command Prompt (Admin) window.
  6. Type the following commands one by one and press ENTER after each line:
    ren C:\Windows\System32\catroot2 Catroot2.old
    net start bits
    net start wuauserv
    net start appidsvc
    net start cryptsvc
    net start msiserver
  7. Restart Windows, and see if you can install Windows Updates now.
