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 one to shrink is the big C one.

    Please do not touch the 100 MB partition, that is your boot partion.

    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.

    Get same update error. Have established that HDD has a healthy Rcovery partition of 517MB.

    Do not think that I should be expected to go through a load of complex and possibly risky procedures to overcome Microsofts problem with this update.

    Me customer, you supplier. Get it sorted!

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