- Windows BitLocker Drive Encryption is a new security feature that provides better data protection for your computer, by encrypting all data stored on the Windows operating system volume. (In this version of Windows, a volume consists of one or more partitions on one or more hard disks. BitLocker works with simple volumes, where one volume is one partition. A volume usually has a drive letter assigned, such as "C.")
- BitLocker protects your hard drive from offline attack. This is the type of attack where a malicious user will take the hard drive from your mobile machine and connect it to another machine so they can harvest your data. BitLocker also protects your data if a malicious user boots from an alternate Operating System. With either attack method, BitLocker encrypts the hard drive so that when someone has physical access to the drive, the drive is unreadable.
-BitLocker lets you encrypt the hard drive(s) on your windows 10 (pro and enterprise), windows 8.1 and 8.0 (pro and enterprise), Windows 7 and Vista Enterprise, Windows 7 and Vista Ultimate or Windows Server 2008 and R2. BitLocker will not encrypt hard drives for Windows XP, Windows 2000 or Windows 2003
