Windows 10 22h2 security update [KB5034441] fails to install with code: 0x80070643

I ran into this issue with my home Windows 10 installation. I was able to use the procedure here: https://support.microsoft.com/en-us/topic/kb5028997-instructions-to-manually-resize-your-partition-to-install-the-winre-update-400faa27-9343-461c-ada9-24c8229763bf to resize the partition.

However - when I got to Step 9 - the output of the "reagentc /info" command did not match the output of Step 2.

Original output:

 Windows RE location:       \?\GLOBALROOT\device\harddisk2\partition3\Recovery\WindowsRE

Subsequent output:

 Windows RE location:       \?\GLOBALROOT\device\harddisk2\partition2\Recovery\WindowsRE

Investigating further - I determined this was because my disk was a older drive using a Master Boot Record (MBR) partition table. After step 6 in the procedure, the quick format changed the ID from 27 (Windows Restore) to something like a 07 (Primary partition).

I needed to add an additional step - what I'm calling "5c"

5c. If your disk is MBR, run set id=27

Following the procedure now, the harddisk and partition numbers for Step 9 and Step 2 match - and I was able to complete the update successfully.

I don't know if this will help anyone else - and of course I can't guarantee anything for anyone who tries it - but it worked for me.

This worked well, and I could install the update without any problems afterward. Just be careful when selecting disks and partitions of course. In case you're not comfortable with doing this then I suggest using the Show & Hide Updates tool that another person with the name "NumskyHusky" mentioned here. I tried it as well at first and it hides this update in case that is enough for you now until Microsoft provides a better/easier solution.

The link that "NumskyHusky" provided for the Show & Hide Updates tool is: (just so that everything is in one answer) https://download.microsoft.com/download/f/2/2/f22d5fdb-59cd-4275-8c95-1be17bf70b21/wushowhide.diagcab

But windows, Mac, chrome os and Linux are really the only ones. The last 2 are the only other competitors and they both have their problems, chrome is not having enough stuff and Linux since it seems like a pain to setup

Why does everybody run to Mac when Microsoft updates are in error. Its as if Apple and Microsoft are the only options.

Ah, did not know that, so thx for the info, cheers
