That's a bit of a weird statement.Windows Vista was pretty bloated, Windows 7 runs wayyyyyy lighter. And those Win compatibility checks are not worth much. They always tell "Computer says noooooo" if the PC is more then 2 year old. But if a PC was fine running Win XP it's fine running Win 7 as well. Only really weird hardware like Creative Sound Blasters are not always working fine.
AS for me, I run Windows 10 just fine on a machine that came out together with Vista
I mentioned only the compatibility check to be brief.
I wasn't aware that those compatibility checks should just be ignored, and didn't want to upset the apple cart just to find out that it was right. But also, I have a very old printer that I still like to use, but can't get drivers to suit Win7 and later. There might have been other issues, too. I can't remember. That was some time ago now.
There are also software issues with later versions of the OS. I have some pretty old stuff that works fine on XP, but not on later versions. I didn't go into full detail in my reply in this thread because it wasn't relevant.
And I'm surprised that you feel that this is important enough to dredge up.
