Done 3 W.U. on machines with all hardware requirements from 19043.1081 to 22000.51, they all completed without any show stopper.
Only one minor annoyance to note that was common to all 3 upgrades, the taskbar was not showing the original pinned icons even thou they were all present, but not visible.
Easy to fix by just putting back the alignment to the left instead of the default center and clicking once on the empty spaces where each icon was originally set. They all showed back up one at the time.
After that everything on the taskbar looked fine.
Did a restart and checked for updates which downloaded and updated .NET kb5004034.
Another minor issue on the Lenovo Yoga 920 laptop, the update installed an older video driver than the one that was previously installed.
Display Adapter Intel UHD 620 had driver 27.20.100.9466,
W.U. installed 27.20,100.8681, I reinstalled the later one after all was done.
