My PC meets all the criteria, but the MS list of supported machines is apparently a bit hit/miss. Because I like to keep my PC and laptop on the same OS, I've stuck with Win 10 because one of my machines isn't on the Win 11 list. I upgraded my wife's PC to Win 11 for her and she, not being a 'power-user', finds it OK. Having had a good look at it myself, I definitely agree with earlier posters who don't rate it. There's a lot missing, and a lot of the changes are just change for change's sake.
