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 Windows 7 and Windows 8.1 operating
systems. It is supported in the Ultimate and Enterprise editions of the Windows 7 and Professional and
Enterprise editions of the Windows 8.1 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.

Windows operating system, or search for "Microsoft Windows BitLocker Drive Encryption Step-by-Step
