Windows 10: KB5048667 fails/ schlägt fehl

My PC supports all hardware requirements for Win11. It came with Win10, but I installed Win11 on the first day. All updates worked until the update KB5048667 came on December 13, 2024. The error message is always 0x80070002, "File not found". Using Copilot I was able to determine that I am probably missing DLL files: "muweb.dll, wuctui.dll, slbcsp.dll, sccbase.dll, wuaueng1.dll, gpkcsp.dll, msxml.dll, qmgrprxy.dll, wuapi.dll, browseui.dll, wuaueng.dll, shdocvw.dll, mshtml.dll, initpki.dll, qmgrprxy.dll, initpki.dll, msxml.dll, wucltui.dll, wuweb.dll, wuapi.dll, wudriver.dll". I cannot register

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.

 

KB4025339 Fails Install 0x80070564

Thanks
I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
Did step 3 KB has downloaded but fails to install.

If Eagle's suggestion doesn't work I'll try EdTittel's suggestion

Tried bothe Eagle & Ed 's suggestions - do not work. Anyone else?

I have noticed that the latest update for my nvidia drivers has failed to update. Wondering about that!
