Using Windows BitLocker Drive Encryption
To help protect your computer against unauthorized access, be sure to use drive encryption software, such
as Windows BitLocker Drive Encryption.
Windows BitLocker Drive Encryption is an integral security feature of Windows 7. It is supported in the
Ultimate and Enterprise editions of the Windows 7 operating system. It can help you protect the operating
system and data stored on your computer, even if your computer is lost or stolen. BitLocker works by
encrypting all user and system files, including the swap and hibernation files.
