Slide 10 of 17
BitLocker
One feature that's gotten a fair amount of press but will be available only in the Ultimate and Enterprise editions is BitLocker, a way to encrypt your entire hard drive. By encrypting the contents of your hard drive, hackers will have a harder time benefiting from the theft of a laptop. Unlike third-party drive encryption, which requires you to log in, then boot into Windows, Microsoft combines these steps for faster access to Windows Vista.
