Read HDD Serial In Vista?

Mar 20, 2009

I have a class which reads the serial of the users HDD, basically so I can generate a unique license for that user based on HDD serial and other things.

This works fine in XP where UAC isn't an issue. However, when run on Vista it pops up security warnings and won't continue unless you turn UAC off!

Is there a "safe" way of reading this information without Vista throwing its lunch up?
