Right now I'm on Windows 7, upgraded from Vista a couple months, and right now I hate myself for not upgrading sooner! Everything has just worked better since the upgrade, and one of my favourite things is that I can actually alt-tab out of games at a decent speed, on Vista it took 1000 years with most games, everything has just been quicker and nicer .

I've got a spare partition which I plan to put another OS on, just to play around with, problem is I don't know which one yet xD.

Updating.
I use Windows 7 on this computer but on my other laptop that I just got back (my sibling had it) I will be putting Windows XP on it.
Why you may ask?
Because it is much easier to work with and will be much faster for Ratting.
