Few comments about Win 11 22H2 Upgrade.
By now I dealt with the 22H2 upgrade on few computers that ran 21H2.
Clean Install is smooth and does not seem to yield any problem.
InPlace Install is another story.
All of the computer upgraded (whether Home or Pro version) kept working well after the Upgrade.
But few Computers while in general working OK yield an Update problem. Error 0x800f0806
The Update system got stuck on one Update file and as result froze the update system.
Solution.

Download the top file.
2022-09 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5017321)
This will download a
windows11.0-kb5017321-x64xxxxxxxxxxxxx
.msu file to your computer
Open the file and let it run (it will take few minutes). Basically it installs Few Updates that preceded the Update that does not work.
When the MSU file finish restart the computer, go back to Update and Retry. At this point the Bad Update will download and install correctly.
