I think it was windows 8 or 10 that introduced the new menus which I found somehow both too simplistic and harder to navigate. And then sometimes you get lucky and figure out a way to open the old menus to do what you actually want.
I think Windows 7 was my favorite as well.
Another thing that it has over XP is that it's better at providing a minimally usable environment post-install, with a better payload of default drivers. I don't miss booting into 256 color 640x480 and trying to get all the hardware in a functional state without a network connection like was a frequent occurrence with XP and older.
Or that's merely the justification to push back against the designers…
I use macOS now and basically hate it.
(but to be honest I have never used Windows 11 and barely used 10)
Also I use a lot of audio softwares and it's hard to run them on Linux, I would need to try how much those download managers (another rant worthy subject) and Windows VSTs can really run on Linux. But when I get a new PC I will.
That's maybe 11's single saving grace: it course corrected and Fluent actually looks pretty good. If only the rest weren't awful.
NT4 had a lot of issues. Good foundation, but not 'peak'.
(EDIT: Actually maybe it was Vista that introduced the inexplicable massive installation size bloat? My memory is fuzzy there)
This was fixed in 2010, about 15 years ago. And it's still the nicest looking UI of any desktop OS to this date:

It's what "liquid glass" wishes to be.
