August 07, 2007 (Computerworld) -- When Microsoft announced that Windows Vista was going to be available in multiple editions, curiosity turned toward the higher-end versions of Vista targeted at corporate environments (Vista Enterprise) and enthusiasts (Vista Ultimate).

In plain language, BitLocker is an on-disk encryption system that encrypts the computer's boot drive, making the system data on it unreadable to unauthorized users -- someone who's just made off with your laptop at the airport, for example.
