Bitlocker: how recover the recovery key


my company requires me to use BitLocker on my computer hard-disk.

Today I have discovered that after Windows updates, it can request a recover key.

So save it for future requests, it's possible to recover it, for an already BitLocked drive, using the following command from an administrative command line (Windows key, type "Command Prompt", right click, "Run as administrator"):

   manage-bde -protectors c: -get

Where C: is the drive whose key you want to recover.
