>Sometimes I look at macOS, Windows 10. Apart from some UI facelift I dont even remember a single user feature

The user "feature" that comes quickest to mind for Windows 10 was the first run of calc.exe showing a popup notification begging for a 5-star rating in the Microsoft Store.

The fucking CALCULATOR. Literally the first and most basic function any computer ever had, which has had NO ui changes in the million software and hardware permutations for 70 years, because it's already perfect. Something has gone unfathomably, fundamentally wrong with how Microsoft works internally.
