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.

    Worked for me, too. Don't like having to go into the bowels of the OS. I fear that I'll make an unrecoverable mistake or the directions given don't provide the same response on my PC and I'm lost. It appeared to me, however, that if I didn't fix this problem, I would never be able to install another update as the updater would always open with this error and no way to get around it. Fortunately, this procedure for expanding the partition did work and solved my problem with update error 0x80070643 on update KB5034441.

    I won't do anything. I'll just wait some time for Microsoft to fix it
