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.

    Believe it or not, this issue is not only occurring on Windows 10/11 computers, but on Server 2022, as well! It's a different KB number, KB5034439, for the server update, but it's doing the same thing with the Windows Recovery partition. This is happening not only on in-house servers, but VM's hosted in Azure as well.

    I sure as heck don't want to go around having to muck with partition sizes on my active production servers. That is definitely NOT a good solution.

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