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.

    Well I did this:

    KB5028997: Instructions to manually resize your partition to install the WinRE update - Microsoft Support

    But now it won't let me re-enable the WinRE.

    So what now?

    Yup same problem here.

    I've been using Windows 10 for over 10 years now.

    First time a security update (the ones on the 2nd Tuesday of every month) didn't install and got an error message.
