Eh, created a local account. Ran through the same scenario to repeat the problem. Same same. I'm moving on. I'm just chasing weeds with this one. The good thing is, all devices are installed cleanly and no reported problems. File Explorer (explorer.exe) hangs on this one step, so its a software issue that will probably be resolved in the MS patch down the road. Maybe this is a bug they aren't even concerned about since they are trying to retire the Control Panel all together.
I posted a message in another forum, but I haven't received any responses yet. I'm posting here too, to give it more exposure. I'll leave the link instead of retyping all the information.Control Panel: Computer selection causes (Not Responding) | Windows 10 ForumsW10 Home Version 21H1 (OS Build 19043.1237)
