WIN8 Upgrade BitLocker Drive Encryption feature

Now we have a growing variety of personal computers, whether it's desktops, notebooks, or tablets, we have become an indispensable partner in our work life, and the data in these devices is the most important, and they need to be protected, whether they are working documents or personal photos. Win8 system, in addition to providing picture passwords and other secure login protection, but also upgraded the drive Security Encryption tool--bitlocker (mobile device corresponding to the function of BitLocker to go), we can use it to specify the drive, especially mobile storage devices to do data security.

Note: Win8 Professional Edition and WIN8 Enterprise Edition support BitLocker feature, WIN8 and win RT do not contain BitLocker function. In addition, if a BitLocker-encrypted drive is formatted, both data and secure encryption protection are lost.

BitLocker in Win7 can only encrypt all data and free space on the target drive, and the encryption process takes a long time if the drive volume is large. In the Win8 BitLocker encryption Service, the user can choose whether to encrypt the entire volume or only the used space. If the user chooses the "Encrypt only used disk space" option, Win8 encrypts the drive portion of the data in the process of encrypting the drive, and the blank available disk space is not encrypted, which can effectively speed up the drive's encryption.

Below we detail the use of BitLocker Drive Encryption in the WIN8 system details and usage, a total of three steps: Enter the encryption interface, drive Encryption operation, after the use of encryption.
