Windows 10 update KB5034441 fails to install - 0x80070643

This will probably the only post I do for Windows ever, happened to do support for a PC over Christman holiday season.

Thing is, security update KB5034441 fails to install with code 0x80070643. Of course, there can be multiple reason, but this Golen article (German) was spot on: the Windows recovery partition needs to be increased.

It refers to a Microsoft support page which has instructions for the command-line how to shrink the system partition and grow the recovery partition. Very nice incarnations :-)

A appreciate the user friendlyness of tools I've never heard of: reagentc, diskpart. After that (no reboot necessary), the update completes installation within seconds, very nice!
