    This is the update about the "PrintNightmare" vulnerability. Here's my situation:I downloaded the update through Windows Update yesterday. After clicking "install," things went as expected, until it got to "Installing: 100%" where it just sat for a good half hour. Having run out of patience, I went to the windows power button where it did not indicate any updates were awaiting a restart and did a restart.This took some time, with a long "Windows is getting ready, don't turn off your computer" message, which it eventually started the upward percentage climb and completed the restart — the sor

    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.

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

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

    Howdy Folks *Smile

    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.
    *Cool
