Wel there is a free way in which you download first uTorrent or bitTorrent or something that opens .torrent files, i use uTorrent
Then set all of that up and type in
vista transformation pack
or something along those lines and it'll show you your choices
or theres a none free way which is buying vista
i have a thought you might wanna do it the free way though
i dunno wether its illegal but i would recomend dpwnloadin a transformation thing that doesnt mess with the registry files cuz if you dont like it and try to take it of it will leave those files there and wont give you the XP files back
