How to reset Windows Update components in Windows 11/10 to fix the update issues? Read this post and you can find some ways to do this task.

First, I realize this is late as the Dec 2024 updates dropped today. However I hope it will help someone who is as bewildered as I was. It's pretty serious if WUP does not work.

I ran into something I have never seen before after installing the Nov 2024 Update KB5046633. I installed it successfully on a VBox VM using the MSU as always. After the final reboot everything looked good and I proceeded to install the rest up the updates using WUP.
First I got a list of updates using a C# utility I wrote
Updates Ready To Install
------------------------
1> Windows Malicious Software Removal Tool x64 - v5.130 (KB890830)
2> 2024-11 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 23H2 for x64 (KB5048163)
Next I made sure the required Services were running
BITS (Background Intelligent Transfer Service
CryptSvc (Cryptographic Services
RPC (Remote Procedure Call (RPC)
UsoSvc (Update Orch Service
wuauserv (Windows Update
Then, after creating a System Restore Pt, I was ready to start WUP
Settings > Windows update
Get the latest updates as soon as available =OFF=
Windows Malicious Software Removal Tool x64 - v5.130 (KB890830)
Download error - 0x80004002
2024-11 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 23H2 for x64 (KB5045935)
Download error - 0x80004002
At this point I tried everything I could think of including the Windows Update Troubleshooter and rebooting.
The errors persisted. Next I found a MiniTool article with a VERY complete list of what to do if WUP
is broken. It included references to a service I have never had reason to deal with
appidsvc (Application ID
As soon as I started this svc everything worked. All I can surmise is that M$, in its finite wisdom, changed something and didn't tell us.
