BitLocker Drive Encryption supports scripting and can be controlled through the Windows Management Instrumentation (WMI). BitLocker configuration settings can also be managed by using Group Policy.
On a remote computer, WMI is the recommended way to turn BitLocker on or off.
For more information about using WMI to manage BitLocker, see BitLocker Drive Encryption Provider (http://go.microsoft.com/fwlink/?LinkId=67030).
