    Failed update to 21H1?


    It is showing as installed in feature updates under update history: but the System/About is still showing as 20H2: How do I resolve this? I tried to download and run the Windows 10 Update Assistant, but that didn't change anything, after downloading and attempting to install I got an "Undoing changes made to your computer" message part-way through.

    :)

  2. 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!
