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.

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!

Iunderstand the frustration if things are not working fine as expected.

Please help us with below details,

          When you say "If I sign in under my user name I am in some earlier version", which version you are referring to?
          
        • 
          Did you made any recent changes to your computer prior to the issue?
          
        • 
          When you say “I cannot access the start menu and am limited to IP as a browser” Is it refers to Microsoft Edge?

All Gmail links fail

Thanks to Caledon Ken...your suggestion had no effect.

Thanks to bro67...Interestingly enough the Gmail link to this forum reply actually worked, as did your link to "How to Fix....." I tried steps 1 and 2 without success. Step 3 gave me the following screen, which didn't look like the article described. At any rate, the probem is unchanged...screenshot follows.
