    Windows 10 Pro Cumulative Update for 20H2 2021-07 KB5004945 Failure


    My Win10 Pro HP Pavilion G6 fails to update to the recommended cumulative update 20H2, 2021-07, has attempted multiple times but right after it hits 100% I get the blue "we couldn't complete the updates" screen. Not quite sure what's wrong with it, have troubleshooted and the System Recovery drive partition is at 500.03MB and my network connection is strong. Any help would be greatly appreciated. Have attached the update history.

    :)

    Seeking advice on Updating to 21H1 with KB5004945 on my doorstep.

    If you are on 20H2 before KB5004945 then you'll still be on 20H2 after KB5004945.

  3. Seeking advice on Updating to 21H1 with KB5004945 on my doorstep.

    Windows 10 Pro - Version 20H2 (OS Build 19042.1052)

    With talk about 21H2 coming soon (and Win-11), I'm ready to move up to 21H1 (from 20H2), but just received July's KB5004945, 2021-07 Cumulative Update for Windows 10 Version 20H2 for x64.

    Normally I'd wait on a monthly Cumulative Update being tested by other brave souls. Perhaps I should stay with 20H2 for a while longer. (?)

    TIA to all who read this post and to those who reply.
