What you want is to login to Windows 11 with a Local Account rather than a Microsoft Account. There are a few ways to enable use of a Local Account with Win11. This article details two methods, one involving a clean install via Rufus and one via converting your current installation to use of Local Account.
I think this is true, but hope it's not and want to make sure. I'm now using Windows 11 (not by choice) and can't use my new Dell Inspiron 3910 (nice machine) WITHOUT entering a Microsoft account password or PIN. That is, I cannot simply turn on my own personal computer, fully paid for, in my own home without proving to the operating system that I have a Microsoft account password of some sort. I don't care who in the house uses the machine, and I'm not at all worried about file security--I am, however, irritated by not being able to just get to work without the hassle of creating/maintaining a PIN or password (which, of course, are written down next to computer just like they are next to millions of other computers). Thanks very much if anyone knows if I can simply push the on/off button and get to work.
