Sheesh man, you try and give some tips and suddenly everyone is on your case.
I don't now if people know this because there's such a stigma attached to it, but bittorrent has quite a few legitimate uses. I've used it to transfer large files back and forth with clients with great success.
But, even that being aside, if this guy wants to torrent stuff, or he wants to not have an active anti-virus, or wants to forgo the use of an imaging program so he could restore his current state without having to reinstall all his programs, that's his business. There's also several sites out there that help you customize a Windows ISO so it installs the exact version you want with the options you want, heck even with preinstalled programs. It's all useless without your product keys of course, but creating a customized ISO doesn't really freak me out on the level of an old school warez user plugging their mods (which this isn't).
