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.

    The update fails on WIN10 when you don't even have a recovery partition.

    The update for WinRE shouldn't be applicable when a WinRE partition is not found.

    My Server 2022 boxes have the same issue with that respective KB.

    Patiently awaiting a re-release.
