This post is just a simple cheat sheet for using BitLocker on a Windows Computer.
Turn Bitlocker ON or OFF and set a pre-boot PIN code.
Start cmd with elevated permissions to run the manage-bde command.
Turn on encryption and create a recovery password:
manage-bde –on C: -recoverypassword
Store the recovery password on a safe place to prevent data loss and reboot the computer.
Check encryption status of the disks:
manage-bde –status

Start:
gpedit.msc
Go to:
Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives
Edit:

Set (see image below):
Require Startup PIN With TPM

manage-bde -protectors -add c: -TPMAndPIN
And enter the desired PIN code.
That's it!
Turn off encryption on disk C:
manage-bde –off C:
The gpedit.msc setting:
