crack of vista or xp

so ive been looking around for these and i'm not sure how big the actual OS is supposed to be. im not too worried about viruses.  should i just say fuck it and download a linux distro, or should i get a crack of xp pro? oh yea, how big are the files supposed to be for xp

XP pro-lite is only a couple megabytes, you can download it here at

Go look on thepiratebay.org for all your warez torrent metafile needs. Of course, you can always take the liberty to dual boot XP and some Linux distro.
