It was on one of my useless test installs before i announce the updates of the Updates Overviews. My wife has such a crappy emmc in her laptablet transformer book, but 20H1 is already offered for ages on it, actually the day after it went public, but she is to much into the store games, so i am not allowed to upgrade it atm
I manually add wsus.ds. to WU links mainly to avoid this rare issue https://forums.mydigitallife.net/goto/post?id=1547066#post-1547066
It's an issue of hypervigilance. Give it another 15 minutes. EDIT: That was anticlimactic. We're officially at 630 now.
kb4589212 <- this download was broken at first but is working now for 2004. Is there notes on what this is?
