Answers Note: Red font color or gray highlights indicate text that appears in the Answers copy only.
Encryption can protect the data on your device by making it only accessed by people who have authorization. If device encryption is not available on your device, you might be able to turn on standard BitLocker encryption instead.
Note: BitLocker is only available on these Windows versions:
- Ultimate and Enterprise editions of Windows 7
- Pro and Enterprise editions of Windows 8 and 8.1
- Pro, Enterprise and Education editions of Windows 10
In this lab, you will enable BitLocker encryption on a removable data drive and on the computer system drive.
- PCs running Windows
- A removable USB storage drive
Part 1: Use BitLocker to Go
In this part, you will use BitLocker to Go to encrypt a removable storage drive.
Step 1: Encrypt the removable drive.
- Insert removable drive, such as a USB drive into the computer.
- BitLocker is off by default and must be turned on for each drive that needs encryption. To turn on and configure BitLocker navigate to Control Panel > in Small icons view, click BitLocker Drive Encryption.
- Under Removable data drives, expand the list as needed. Select Turn on BitLocker for the desired removable drive.
- In the Choose how you want to unlock this drive window, check the Use a password to unlock the drive and then enter a password. Click Next to continue.
- In the How do you want to back up your recovery key, select either Print or Save to a file and then click Next.
- In the Choose how much of your drive to encrypt window, select Encrypt entire drive and click Next.
- If you are prompted with the Choose which encryption mode to use window, select Compatible mode and click Next to continue.
- In the Are you ready to encrypt this drive window, click Start encrypting.
- After a few minutes, the removable drive will be encrypted. It can now be removed.
Step 2: Access the encrypted drive.
- Insert the removable drive previously encrypted in the previous step into the USB port on the computer.
- Navigate to the USB drive in File Explorer or Windows Explorer and open the USB drive. (If you are unable to open the USB drive, right-click the encrypted drive, click Unlock Drive.)
- Click the More options button. Notice there is an option to enter the recovery key. If the password is forgotten, the saved or printed recovery key from the previous step can be used to unlock the drive.
Why is it important to save a BitLocker recovery key?
The recovery key is needed for you to gain access to the computer in the event the password is forgotten, or in the event of certain hardware problems, such as a motherboard replacement or hard drive crash, or even after performing a BIOS update. Without it, there is no way to access your data.
- Enter the password to unlock the USB drive. Now you are able to access the content on the encrypted drive.
Step 3: Decrypt the drive.
- Navigate to the Control Panel > in Small icons view, click BitLocker Drive Encryption.
- Select the encrypted removable drive. If the drive is locked, enter the password to unlock it. Click Turn off BitLocker.
- Click Turn off BitLocker when the message notifying you that the decryption process could take some time. Note the warning message so you do not damage the content on the drive.
- Click Close when the decryption process is done.
Part 2: Encrypt the Operating System Drive
In this part of the lab, you will use BitLocker to encrypt the operating system drive.
Step 1: Turn on BitLocker.
- Return to Control Panel > System and Security > BitLocker Drive Encryption to turn on BitLocker for the operating system drive.
- Under Operating system drive, select Turn on BitLocker.
Note: If an error message appears stating the device cannot use a Trusted Platform Module, some additional steps must be taken to allow additional authentication at startup. Click Cancel and perform these additional steps:
1) Type gpedit.msc in the Windows search to open the Local Group Policy Editor.
2) Expand Administrative Templates in the left pane and click Windows Components.
3) In the Windows Components list, select BitLocker Drive Encryption. Select Operating System Drives. Select Require additional authentication at startup.
4) Inside the Require additional authentication at startup window, select the Enabled button, then click Apply and OK to close the window.
5) Close Local Group Policy Editor to return to the BitLocker Drive Encryption window and click Turn on BitLocker.

What is the function of a TPM in relation to BitLocker?

Step 2: Turn off BitLocker.
- To turn off BitLocker return to Control Panel > System and Security > BitLocker Drive Encryption to and select Turn off BitLocker.
- Click Turn off BitLocker to decrypt the drive. This process may take a while depending on the size of the drive.
