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.

    In addition to the suggestions given by other posters for using the instructions on the following page about resizing the recovery partition:

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

    I also found the following page helpful which additionally describes how to get a missing winre.wim file in case enabling the recovery environment with "reagentc /enable" fails after resizing the partition:

    https://www.libe.net/en-windows-recovery-partition

    Be sure to note the comment at the bottom about the difference between disk IDs for disks using MBR vs. GPT partition structure.

    I was seeing the problem on 3 PCs that have been migrated to SSDs with Samsung Magician, so I wonder if this problem may be a side-effect of the re-partitioning that happens during the migration process.

    Also have this issue. Advising the average PC user to change the partition sizes in command line is a recipe for disaster. Waiting for MS to release a tool/fix.
