20240520 UPDATE: I just ran winupdate on an ancient win10 surface and after the same 643 error two more times, and running through all the available updates, it’s now reporting I’m up to date. yippee.
I guess the latest update finally fixed it, at least on the Surface.
Anyone tried and succeeded? Not too awful plodding through the resizing? Tips to avoid destroying a partition and having to reinstall the os?
Lucky for you! Twice over the years I have had Windows 10, the system failed to come back up after a windows update and the ability to uninstall the most recent update through the recovery partition saved me.
