may I ask why?
Personally I am fine and anchored to Win, as my professional programs are Win only.
If you are a pro linux user, then I do understand you, as the best OS can be what you make yourself, but personally I am okay with programming, not a fan of it.
W7 is simple, windows 8 is a nightmare. I use a win 8 laptop and at school, and holy crap, it is unusable
But windows 8.1 is fine. I like the tile screen, as it is acting as a search bar and turn on off centre, although I would be happier what is in win 10.
Multi monitor support is good, really good, and it uses my Fx 8320 better than Win 7. Kernel part seems to be fine
