The majority of that torrent was junk -- something like 20 GB of Microsoft's (freely available) patents downloaded from the USPTO, a couple of DVD rips of documentaries tangentially related to Microsoft (like Revolution OS), and a bunch of wacky conspiracy videos downloaded from YouTube (Bill Gates 5G nanoprobe vaccines, etc).
All of the actual content was available elsewhere as much smaller downloads. In particular, the Windows 2000 and XP leaks are distributed as a single 3 GB archive ("nt5src.7z").
