The fact that "a portion of the Windows OS has leaked on peer to peer networks" shows the real security of MS. A partner in the WISE program, once one of two companies that were handed Windows source code to use WinAPI on *nix, called MainSoft apparenltly is responsible for this leak. Well, though MS writes it off as next to little, or so they say, search for "source", option: Kazaa, and you will be amazed. My computer stopped responding when I tried to sort the massive amount of sources by size. The source will not compile correctly, nor into an OS. It is the source for Service Pack 4 on Win2k, and NT machines.
