What is BitLocker?
BitLocker is a security feature added in Windows Vista (also available in any higher version) that protects a computer’s file system. BitLocker encrypts disk drives and their contents. When encrypted, others cannot see your files even if the computer had been stolen or the hard disk was taken. BitLocker also works on removable storage drives. In order to access an encrypted drive, users must authenticate/login to access the data.
Setting up BitLocker
The BitLocker setup wizard is available in either Windows Explorer or the Control Panel. Remember, the operating system should also have the Trusted Platform Module (TPM) to fully take advantage of the encryption features.
