This comprehensive guide is specifically tailored for securing your personal home PC or Mac. It's essential to note that Seattle University's managed devices come equipped with state-of-the-art security measures pre-configured, ensuring an elevated level of protection by default.

Introduction

BitLocker is a built-in encryption feature in Windows that helps protect your data by encrypting the entire drive. When enabled, it safeguards your sensitive information from unauthorized access, adding an extra layer of security to your system. To ensure your data remains protected, follow these simple steps to enable BitLocker on your Windows computer.

Note: Before proceeding, it's crucial to have a backup of your important data. Enabling BitLocker without a backup may lead to data loss if unforeseen issues arise during the encryption process.

Step-by-Step Guide

  1. Click on the Start button (Windows logo) located at the bottom-left corner of your screen.

  2. In the search bar, type "Control Panel" and press Enter.

  3. In the Control Panel window, click on "System and Security."

  4. Under "System and Security," click on "BitLocker Drive Encryption."

  5. If BitLocker is not available for your system, it may be because your device does not support it. However, most Windows editions include BitLocker, such as Windows 10 Pro and Enterprise.

  6. Once you're on the BitLocker Drive Encryption page, click on the drive you want to encrypt. Keep in mind that the system drive (usually the C: drive) is the most critical one to protect.

  7. Click on "Turn On BitLocker" next to the drive you selected.

  8. You will be presented with two options to unlock the drive. Choose one of the following:

    a. "Use a password to unlock the drive": You can create a password that you'll use to unlock the drive each time you start your computer.

    b. "Use my smart card to unlock the drive": If you have a smart card, you can use it to unlock the drive. This is a more secure option for enterprise environments.

    c. "Use my TPM (Trusted Platform Module) to unlock the drive": If your computer has a TPM chip, you can use it to unlock the drive automatically during the boot process. This option is only available if your computer supports TPM.

    d. "Save the recovery key to a file": You can save a recovery key to a USB flash drive or a file, which you can use to access the drive if you forget your password.

  9. Follow the on-screen instructions to proceed with the encryption process.

  10. Depending on the size of the drive and the amount of data, the encryption process may take some time. Your computer will be usable during this process, but performance may be slightly affected.

  11. Once the encryption process is complete, restart your computer to ensure BitLocker is fully enabled.

That's it! Your selected drive is now encrypted with BitLocker. Every time you start your computer, you'll need to enter your password or use your recovery key (if you chose that option) to unlock the drive and access your data. This additional security measure helps protect your data, even if your computer is lost or stolen.
