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've had the same issue - Not sure why the other previous installations all worked fine but not this one. Tried all the above tips to release disk space, clear system images, bitsadmin, sfc repairs everything.

    Do we have any official response from Microsoft, other than "Well, you could always re-install!"?

    Thanks

    So the average John Doe user has to repartition the disk drive. Gee, that's really simple. Maybe I'll just turn off updates because I'm too stupid to use a Windoze computer.
