for me,this time is not wasted, starting formation, going eatin/tv/shower etc, windoof is installing, type some shit in, and go doing anything again, installing drivers and almost ready, just installing shit like xfire, qip, winamp and so on. then some games, which are worth installing, there we are, clean computer...my documents are all on an external drive, so i dont have to worry about them...
linux is not an option for me, cuz newest games arent supporting it...usually

Well I would still say that you could avoid that by having an updated Windows + good AV.

Just my suggestion.
