Windows 10: KB5004296 fails with 0x800f0990

This special update was issued to users who were in beta channel but moved to release preview. Why is this update failing and why is it not in the microsoft update catalog. Please advise

:)

 

KB5004296 Windows 10 Insider RP 19043.1149 (21H1) or 19044.1149 (21H2) Insider

Install initially failed twice with 0x800f0990 error. Ran SFC and then DISM series (components were repairable), but still no go. Deleted KB5004296 install files from SoftwareDistribution\Download and tried again with a fresh download. Failure! *Sad

 

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!
