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!

 

Multiple updates fail, Windows Defender won't start, can't activate

Alright so ... the first step did not work. It got stuck at verification 100 percent and I verified that it was not doing anything else via task manager. The second step, followed by the first step again, also did not work. But the third step did! After running the third step, Windows Defender works, those three updates installed fine and I'm good to go!

Well ... almost. I still can't activate. Does anybody have any advice there? I opened Microsoft Edge, went to the Windows Store app and then checked but I still am not activated. I've tried clicking the activate button around 200 times (had an auto-clicker attempt it, even)

EDIT: The activation error I'm getting is Error code: 0xC004F012 The Software Licensing Service has reported that the call has failed because the value for the input key was not found.
