Hi! After resize, did you run: reagentc /enable To re-enable WinRE

Yep, a known issue. Fix error 0x80070643 for Windows 10 KB5034441 update - Your Windows Guide Windows 10 KB5034441 security update fails with 0x80070643 errors (bleepingcomputer.com)

Just increase the recovery partition space to 1 GB If you are not familiar, you can use the video tutorial on YouTub.. Search "Create recovery partition in Windows 10/11 UEFI → IT Army"

I have given up on getting anything with this to work: even the IT expert I rely on for such matters, states that the effort to increase the space of memory does not work, as Microsoft states; this is beyond ridiculous.
