    Update completes and fails when done


    Im trying to install 21H1 and 21H2 but it always gets stuck at 99% and then completes after some time and then says then the update failed. I have tried installing 21H1 4 times now and I still cant install it, I even waited 30-45 minutes for the updates to complete and did the restart for it and then the next day it isn't installed. Any know why I cant install my updates?

    :)

    Windows Updated(16299.309).KB4088776 Restart is required to complete.

    Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

    Thanks for the suggestions and for the time to respond Update completes and fails when done :) Best regards.


    And thanks for the tip of that program, I'll have it on my list.

    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!
