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 (referred to as BitLocker) 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 can encrypt all user and system files, including
the swap and hibernation files.
BitLocker uses the TPM to provide enhanced protection for your data and to ensure early boot component
integrity. A compatible TPM is defined as a V2.0 TPM.
To check the BitLocker status, go to Control Panel, view Control Panel by Category, and click System and
Security ➙ BitLocker Drive Encryption.
For more information, see the help system of the Windows operating system, or search for "Microsoft
Windows BitLocker Drive Encryption Step-by-Step Guide" on the Microsoft Web site.
Disk Encryption solid-state drive
Some models might contain the Disk Encryption solid-state drive. This encryption technology helps to
protect your computer against security attacks on media, NAND flash, or device controllers by use of a
hardware encryption chip. For the efficient use of the encryption feature, set a hard disk password for the
internal storage drive.
