Hands-On Exercise: Recover Access to BitLocker Encrypted Volumes
In this exercise, we will regain access to the BitLocker encrypted volumes. The easiest
way to simulate this on your system that is TPM enabled is to turn off TPM and restart
the computer. Take the following steps when you have an inaccessible volume due to
missing authentication requirements:
1. If the computer is turned off, turn it on. You will be presented with the
BitLocker Drive Encryption Recovery Console.
2. If you have a USB flash drive containing the recovery password, insert that now and
press esc. This will automatically enter the recovery password for you and
restart the computer.
Or, if you do not have a USB flash drive with the recovery password but have the
password available, press enter, and then type the recovery password using the
function keys. Press enter to restart.

Turning Off or Uninstalling BitLocker Drive Encryption
At some point, and for various reasons, you??™re probably going to want to disable BitLocker
temporarily or completely disable BitLocker and decrypt all the encrypted drives. The
most common reason why you??™d want to disable BitLocker temporarily is to perform
updates on the operating system or make changes to the TPM. Either of these actions
would lock the drive and prevent access until a recovery key is entered.
