Microsoft provides users with a powerful BitLocker encryption feature in the ultimate version of the Windows 7 operating system, which was first seen in Vista Systems, and BitLocker secret technology can support both FAT and NTFS two formats to encrypt the protection of user data. You can encrypt your computer's entire system partition, and pages can encrypt removable portable storage devices such as USB flash drives and removable hard disks. BitLocker to go, which encrypts mobile device storage such as a USB flash drive, is the latest feature added.
