How to lock a bitlocker enabled drive even though when the system is running

Usually what happens is that the Windows OS does not allow users to

lock the bitlocker enabled drive once it is opened. They will only

lock the drive if you restart the system.

But here is a trick to lock a bitlocker enabled drive even when the

system is running.

Open the cmd as administrator ( Press WinKey + x)

Type the following:

manage-bde -lock:E

Note: Here E is the drive letter I want to lock. It might vary in your

case.
