  • Open the Power Menu using the Win + X shortcut key and select Run.

Sometimes you may encounter this error when the Windows Update service stops working due to having some corrupted or damaged Windows components. In such a case, you can reset every single component of the Windows Update on your Windows 10 PC and then check if it resolves the problem.

5] Roll-back Windows 10 Update

Oftentimes, Windows 10 installs the updates automatically in the background when you turn on your device. However, if none of the above methods work, then as a last resort you can simply roll back your update to the previous operating system installation. In order to roll back the update, follow the below steps –

  • Click on Start and type “cmd”.
  • Right-click on the Command Prompt and select Run as administrator.
  • In the Command Prompt window, type the following commands and hit Enter after each one.
dir d:
dism /image:d\ /remove-package
/packagename:Package_for_RollupFix~31bf3856ad364e35~aamd64~~7601.24002.1.4 /norestart
  • After executing the above codes, reboot your device so that the changes could apply.
