    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.

    I got it on both my Windows 10 machines. Looks like this is a disastrous update. I can't understand why MS can't produce meaningful error messages specific to a particular problem. It looks like many different issues can generate this same error code.
