I googled the actual KB and found this link: https://support.microsoft.com/en-gb/topic/kb5034441-windows-recovery-environment-update-for-windows-10-version-21h2-and-22h2-january-9-2024-62c04204-aaa5-4fee-a02a-2fdea17075a8. It seems that it updates the Windows Recovery (WinRE) environment, and the tip about resizing the partition for that is valid. You can find the link to the instructions in the KB article I linked.

I did that and the installation passed.

    Fair warning to anyone trying to follow Microsoft's "Advised solution" of messing with your partitions that it can just straight up cause your recovery partition to loose a necessary .wim file which will then, unless you then have a windows machine on the same update version from which you can harvest the .wim file, make it so that you're unable to reinitialize the windows recovery feature at all.

    Not only that but even if you then just delete your recovery partition the update will still continue to fail.

    If this happens it seems that your only recourse for getting a working recovery partition back is to literally wipe your drive and reinstall windows.

    I personally spent all of yesterday dealing with this and dealing with trying to get a matching wim file with no luck.

    So, thanks so much Microsoft. I sure enjoy you erasing hours of work while I'm asleep then destroying multiple days worth of my time because you can't configure your updates properly.

    For me it was simpler: I found out running reagentc /info that my recovery partition was disabled. I enabled it with reagentc /enable and then I retried to install the update from the Windows Update and it worked.

    Thanks for the tip!

    Nah. He took about 5 minutes to say reboot and try to install it on it's own. It doesn't work.
