Sorry to rain on your parade (and I am not showing off either) but I run XP, Vista and Win 7 
. To be more specific - I have a home built dual boot PC XP and Win7, as well as an ancient laptop with Vista on it (with NwN on all three OS's). So choosing just one OS is not possible for me.

If you have more than one OS, vote the best, and if you feel you need to share details, post in comments,
Assumedly you have a windows 7 computer that can also boot to to a Windows XP Drive/partition, technically speaking.
(Your certainly not "raining on my parade" by any means, as a single vote here there really isn't that important, honestly, just big picture...)
