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.

    Excellent! Thanks for the video and/or the link. I had tried the KB5028997 process but suffered from a lack of understanding and it didn't work. The walkthrough in the video (jump to 42:14) gave me the missing info to complete the process and that pesky update finally installed.

    The key part I was missing from the 'KB5028997: Instructions to manually resize your partition to install the WinRE update' was, shrink (shrink desired=250 minimum=250) from the Primary partition (partition 3) and then delete (delete partition override) the Recovery partition (partition 4). Creating and formatting the new partition was simple enough.

    Thanks again,
