Also, agree that Win2000's color scheme was the best looking iteration of the classic Windows look.
No, it just tells a story of what you've been in to years ago.
The color codes burned into my memory are: #aeaedd, #11ff11 and #dddd11. Who wants to guess where these came from?
Windows 10's design is just bland. I don't know why MS went ahead with this soulless design for so many years after Windows 8 came to be.
Windows 11 tries to be nicer but really it's just a fancy cover on legacy designs left over from since Windows 3.1.
My guess is they need it to feel different enough to justify the price tag of a major upgrade.
In reality the changes behind the scene since Windows 7 have been incremental.
It's interesting you say that, since I remember back at the time XP was released, so many people complained about how Windows XP had a "Fisher Price" UI that was distinctly non-professional. (Personally, I always liked XP's look.)
