BitLocker definition

BitLocker is a full-disk encryption feature included with Microsoft Windows that provides encryption for entire volumes. It was introduced with Windows Vista and is also available on Windows 7, 8.1 and 10. BitLocker helps to protect data by encrypting the entire disk volume, including the operating system, user data, and temporary files. It can also provide additional protection through the use of a pre-boot authentication mechanism, which requires a user to enter a password or insert a smart card before the operating system will boot.
