I don't know. I've read rumors that StarForce uses undocumented functions ... so it's rather a StarForce thing, I guess. Or MS makes something towards compatibility, especially with the content industry (for example publishrs) wanting protection for their media (like games).

When you find a big kettle of crazy, it's best not to stir it.
