With the introduction of Microsoft’s new operating system, Windows 7, many new features have been added that were previously unavailable on older versions of Windows. One new feature to Windows 7 is BitLocker to Go. With BitLocker to Go, which builds off the BitLocker program originally developed for Windows Vista, you can now encrypt personal information on USB Flash drives. BitLocker to Go will work on almost every USB flash drive, even including those promotional USB drives that are becoming increasingly popular.
