Have you ever got irritated by BitLocker after upgrading to Windows 10? Well I got as I forgot password to unlock the drive. Keying in BitLocker Recovery key is real pain.
Below are the steps to go ahead and play with it:
Step 1: Open Command Prompt with Administrative privileges.
Step 2: Type below command to get the status of drive
manage-bde <Drive-Letter>: -status

Step 3: Start Decryption by issuing below command
manage-bde <Drive-Letter>: -off
Decryption will be started and you can check the status by the first command.

Step 4: There are many switches. Complete list can be browsed by below command.

Please let us know in case you are stuck with something related to BitLocker encryption.
Thank you !!!
