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....
My RE partition had sat before my main partition - and since you can't shrink partitions at their start (left) with fdisk and I didn't want to boot up a Linux pen drive, I just shrank the main partition at its end (right) and moved my RE partition to the now freed space at the end.
I've made the old RE partition available, but since it's just a few hundred MB, I doubt I'll ever actually use it. :-P
PS: If you do it via fdisk, just make sure you first enable the new RE before disabling the old RE. Otherwise there's nothing that can be copied to the new RE - I've made that mistake and had to get the missing files from a Windows ISO.
