Which windows is best?

[Matthias]

You asked for our favourite Windows but you only included 3 (and not their sub-versions like XP Pro). What if someone completely hates Windows and wants to avoid using it unless they have to (college)? There should be a ''neither'' or ''other'' option at least.

My vote would go too Windows XP Professional.

I doubt he can list every option like Prof, Ultimate, and whatnot for both 32 and 64 bit lol. Also, the question is which windows system, not which operating system. He doesn't have to include Ubuntu or whatever.

My vote would go to Windows 7.
