For win8/win8.1 users, Microsoft offers an official solution that eliminates the need for a separate download tool to operate directly locally to complete a repair task. The Microsoft KB947821 Technical documentation also describes the reasons why the win8/win8.1 update failed: When Windows Update is corrupted incorrectly, Windows Update and win8/win8.1 store downloads and updates are blocked. For example, if a system file is corrupted, the Windows update update may fail or install, and an error code typically appears.
