Many Windows users have reported difficulty in installing update KB5008212 for Windows 10 for versions 21H2, 21H1, 20H2, and 2004; the last such update for Windows 10 v2004 before it officially ends service. Failure can occur if:
- Crucial Services are Disabled – Windows Update service and Background Intelligent Transfer Service (BITS) must be running for successful installation. Failed installation may mean that one or both are not functioning correctly.
- Windows Update Service is Corrupted – Windows updates build up temporary files over time and service components can become corrupted, preventing your system from updating. Resetting the components can fix the issue.
There are several known methods of resolving the issue. Let’s take a look.

Repair Install/Clean Install
If none of the above methods have been successful, then you have no choice but to reinstall the system files.
This is completely reinstalling your Windows OS. Please note: this involves totally wiping your previous system, including all of your personal files, from the disk or partition.
