Equally fun fact (that I just learned): If you later associate a Microsoft account with your Windows 11 Local account and choose "User this account everywhere in Windows" instead of "Microsoft Apps Only", even though your account is still displayed as a local account, there does NOT seem to be a way to disassociate that initial account from your user profile. The local password still works, but even a sweep through Credential Manager and sweeping the registry doesn't seem to prevent the association.
This isn't a massive deal breaker most of the time, but I've run across it on my lab PCs a couple times now, such that they now have a security policy in place that prevents users from signing in on a Microsoft account at all; I had people signing in to their onedrive, associating the whole PC with their account and thereby hosing the machines in question.
OK and the actual reason I posted: My datacenter guy only wants $250 for 2080Tis or 12GB 3060s. 100% that they were mining cards but at least I know the conditions in which they were used. I have to say I'm tempted to buy a couple at least.
