Since I am currently studying CIT (Computers Information Technology) my university gave me an account to a website where I can download a wide range of software, from all the editions of windows 7, vista, xp, server right through to All the visual packages (C++, C#, Basic) and much more.
I would give you all my username and password but they log and track all IP's that download from the site. That would get my account removed. Sorry.
For all of you do the custom install delete the C partition and do a fresh install. That is if you want to do a full install. The full version is on the upgrade disk. Oh and I heard the PB and other torrents were put out there by MS to dial home for a later round up.
