BitLocker Volume Conversion
Applies To: Windows Server 2008
In BitLocker parlance, the term "conversion" refers to either encrypting or to decrypting an entire volume. Encryption of the entire volume occurs when BitLocker is enabled for that volume. Decryption occurs if an administrator chooses the Decrypt the drive option when turning off BitLocker from the BitLocker Control panel or uses the disable option from the manage-bde command-line tool.
