Not sure how that prooves anything if that computer actually run fine or not?
- how many BSOD are you getting or something else malfunctioning
Just installing something does not mean it runs fine IMO.
I think it was some wiki or somewhere else it was listed what instruction sets are introduced in a certain generation cpu's.
- if entire os build on using those instructions software may malfunction
- most software you run most probably are not limited to certain instructions sets unless they mandate Windows 10 or 11 or similar.
