Windows 10: Windows Update 0x80070643 Error Fix -- Screwed up WinRE partition size due to SSD...

After using the microsoft recommended method to manually resize/shrink the primary OS partition by 250 MB in order to increase WinRE partition size so that you can finally install the new windows update 0x80070643 ERROR.

KB5034441 0x80070643 error despite no WinRE volume

Like many Win10 users, I am getting the 0x80070643 error when I try installing the KB5034441 update. The claim everyone makes is that this is due to the WinRE volume not having enough space. But I don't even have a WinRE partition -- I've disabled WinRE and deleted its partition. What is going on here? And will a repair install help? I was considering doing a repair install for other reasons anyway. Is there a way to tell if a repair install would include KB5034441? If it didn't include it, I don't see the point.

I think 1 GB is enough.

I don't think you should make any changes now - a fix is on the way.
