You added every version of windows, then you just wrote "Linux". What were you thinking? I can't stand Windows, slow, too many viruses. The only thing windows has going for it is compatibility. The best version of Windows was 98 or possibly 2000. XP sucks! Uses up way too ram. My crappy 128mb ram comp can barely handle Xp, but I also dual boot Yoper which my computer can handle fine.
