I do believe it will also be designed to catch hacked downloads from torrents.
That is how most of the illegal programs,movies,books,music ect. get passed around the world. I don't think they are worried about you making a copy of a movie as much as they are worried about a 1000 copies of the movie being passed around the world every hour.
Hi there
While not advocating Piracy I'd like to know what possible business is it of Microsoft to check whether I'm downloading Movie torrents -- it's up to the Police (where appropriate) and the COPYRIGHT HOLDERS.
Similarly if I drive a BMW dangerously it's not up to BMW to monitor this but the appropriate competent legal authority / authorities --Highway patrol, local Police, municipal police -if you have them --etc.
Cheers
