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.

    Dansk:

    Der er noget med en gendannelsespartition, som skal ændres i størrelse. Dette burde opdateringen have gjort automatisk. Så findes der programmer, hvor man selv kan gøre det, og så forsøge opdateringen igen. Men gem venligst dokumenter, billeder og andet du måtte have på computeren på ekstern harddisk!!! Hvis nu noget går galt, med ændriung af partitionsstørrelsen!

    Jeg vil anbefale at vente indtil Microsoft udsender en ny, fejlfri opdatering. Det er mere sikkert end at rode med partitioner. Som du kan se - alle og enhver har dette problem

    English:

    It's something about a recovery-partition, which has to be changed in size The update SHOULD have done this automatically. There's programs where you can do it your self, and then try the update again - but please save any documents, photos and other you may have on your computer, onto an external harddisk!!! If now somethig go wrong when changing the size of the partition.

    I will recommend to wait to Microsoft sends a new, error-free update. That's more secure than fiddling around with partitions. As you can see, everyone has this problem

    @XNghia Huynh Your situation is the Recovery partition should be just behind the C Partition. Windows can change the size of the partition if it is able to use space from the C partition to do that. If the partition is just behind C the operation can proceed, assuming there is enough free space in C.

    How full the UEFI System partition is can be misleading. Disk Management always shows it as 100% free, but it isn't.

    You can run the command below in an Admin command prompt. The bytes free number will let you know the actual situation. When the command prompt window closes, the Y: drive letter goes away.

    These commands place a drive letter, y: in this case so you can get a directory listing. Make sure and add spaces in the commands.

    C:\Windows\System32>mountvol y: /S

    C:\Windows\System32>y:

    Y:>dir

    Volume in drive Y has no label.

    Volume Serial Number is A463-307C

    Directory of Y:\

    03/04/2023 05:25 PM <DIR> EFI

               0 File(s)              0 bytes 
    
               1 Dir(s)      **71,465,984 bytes free**

    Believe it or not, this issue is not only occurring on Windows 10/11 computers, but on Server 2022, as well! It's a different KB number, KB5034439, for the server update, but it's doing the same thing with the Windows Recovery partition. This is happening not only on in-house servers, but VM's hosted in Azure as well.

    I sure as heck don't want to go around having to muck with partition sizes on my active production servers. That is definitely NOT a good solution.
