Right now I'm using 64-bit Windows 6.1 (commonly known as 'Windows 7'), while I normally use 32-bit Debian (though I forgot which version exactly). I'm not much of a Microsoft fan.

Windows seven and windows server. I really don't like windows 8 it doesn't have the right look/flow on a normal desktop. Its good for tablets and other touchscreens but not normal desktops (in my opinion)
