Windows Embedded Standard allows you to encrypt your disk drive so it only works together with your hardware.
BitLocker protects against data theft or exposure on devices that are stolen, and offers more secure data deletion when computers are decommissioned.
BitLocker allows you to encrypt the entire Windows operating system volume and any other volumes in your device. All files including system files, swap and hibernation file are encrypted.
Together with a Trusted Platform Module (TPM) version 1.2, BitLocker uses the enhanced security capabilities of the TPM to help ensure that your data is accessible only if the computer's boot components appear unaltered and the encrypted disk is located in the original computer.
Windows Embedded Standard 7 has BitLocker To Go integrated which allows to use BitLocker also on removable devices such as a USB drive.
