I have to say I agree with you! Like I have been using windows 7 ever since it came out and my pc has been running that ever since.
Recently I got a windows 8 laptop just for college and shit nothing special about it apart from the terrible windows 8 OS, I couldn't get used to it and just simply didn't like the whole layout. There is many more features I couldn't get used and simply didn't buy into until windows 8.1 when it at "least" started to get useful. Windows 8.1 is a much bigger improvement over windows 8 , but it simply doesnt get the same feeling from windows xp and 8 (never mind vista). Windows 8 has better "security" and also batter "gaming performance" by about 2-4fps per game if your lucky. It never really tempted gamers to but windows 8 and to this day it still doesnt
Windows 10 in my opinion will be another windows 8 with just a new directX "with apparently better fps across all platforms". Then again I havent tried the windows 10 test preview and would love to here feedback???
Edit: With the Steam OS made possible from the linux OS, then surely Windows are feeling the pressure from the game developers in terms of availability worldwide in the years to come
