I recall the first time I used the new windows 8 UI. It was absolutely horrifying. There were 2 different control panels with different settings sometimes overlapping. The traditional UI in which you could start apps by clicking on desktop shortcuts and manage traditional windows but certain apps including the start menu put you seemingly randomly in the weirdo new app experience where the window took up the whole screen. This was also true of clicking a url link in a different app.

It was bar none the worst desktop interface that anyone has ever released for a computer.

You have asserted without evidence that MS's UI is driven by science and you are assuming that Microsoft's research is in fact any good. Based on consistently mediocre results I have reason to doubt that. To support your position I suggest you actually cite some research instead of assuming it has been done competently.
