So then I have a question about the installation. I'm using Vista home premium 32 bit right now, if I wanted to upgrade to W7 ultimate 64bit then that is a reformat and clean install right? Would I be able to upgrade so I can keep all my files and settings? Also, what is the latest version of W7? If someone could pm me a torrent link that would be great, since I see all kinds of versions and I'm not sure which version I need.
