Using Windows BitLocker Drive Encryption
To help protect your computer against unauthorized access, use the drive encryption software, such as
Windows BitLocker Drive Encryption.
Windows BitLocker Drive Encryption is an integral security feature of some editions of the Windows
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.
BitLocker uses a Trusted Platform Module to provide enhanced protection for your data and to ensure early
boot component integrity. A compatible TPM is defined as a V1.2 TPM.
To check the BitLocker status, go to Control Panel, and click System and Security ➙ BitLocker Drive
Encryption .
For more information about Windows BitLocker Drive Encryption, see the help information system of the
Windows operating system, or search for “Microsoft Windows BitLocker Drive Encryption Step-by-Step
Guide” on the Microsoft Web site.
