Windows update (KB5034441) Error (0x80070643)

I've experienced the same issue with this update, and, despite running through the steps to change the partition size, which also involved getting a piece of third party software as I had two unallocated partitions, one in front, and one after the main Windows partition which needed combining. Having done all of this, the steps still didn't work for me.

What seems to be the issue in my case is that, probably at my own hand, I no longer actually have the WinRE image anyway. So the location can't be set because it doesn't exist anymore at that location. Needless to say, when you finally try to Enable it again, it fails because there's no valid path/image.

This is something I have no idea how to resolve. I saw something about downloading some kind of .wim file, and then extracting something from that, popping it in the Windows/Recorvery file location and then trying to set the path to that, but it all feels somewhat challenging. With the amount of time I've spent reading the articles/info/trying to resize partitions, it probably would have been quicker to just completely reinstall Windows on my laptop (and everything else). That currently feels like the last resort/sledge hammer approach. :o(

I've decided to ignore it and move on. Maybe Microsoft will wake up and fix their mistake.

In addition to thinking "there has to be an easier way", if I recall it seemed like one of the instructions deleted the RE part and had you recreate it -- sorry if not remembering it correctly as again I know there has to be an easier way.

I have not played around with this problem enough to know how to restore the WIN_RE part but my memory is correct somewhere in the command script they have you recreate the partition.

Sorry I can't be of more help on this.

I would not be surprised if MS at some point says 'Upgrade to Win11 and it will fix the problem."

Thanx A lot more help than Microsoft is willing to provide.
