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.

    Thanks a lot Marcus, formatting the disk first solved the problem. Also not necessary to set gpt attributes

    I feel like this might be a dumb question, but the partition that needs to shrink - is it the 100MB System one or the larger one (Primary) that has Boot and Basic Data Partition and the the majority of the drive? I'm assuming it's the larger one but I just want to make sure.

    what are the problems you are talking about ?

    When I solved the problem, no problems occurred in the recovery partition or in WinRE

    The problem/solution is listed here: https://support.microsoft.com/en-us/topic/kb5028997-instructions-to-manually-resize-your-partition-to-install-the-winre-update-400faa27-9343-461c-ada9-24c8229763bf

    Sure, it was yesterday posted on page 2.

    Maybe we had set up our rigs with older Windows version that made a smaller recovery-partition.

    The solution is in fact to enlarge it by 250MB (resize) by taking away 250MB from the OS-partition.

    Unfortunately there are some people with the error "not enough space left to resize". Me for example.
    After releasing my Samsung EVO970 SSDs overprovisioning partition (using Samsung Magician), I was able to resize and it went smooth.
