How to encrypt a Windows computer with BitLocker

BitLocker is available on the following Windows versions:

  • Windows Vista and Windows 7: Ultimate and Enterprise editions
  • Windows 8 and 8.1: Pro and Enterprise editions
  • Windows 10: Pro, Enterprise, and Education editions
  • Windows Server 2008 and later

What you will need:

  • Your computer and your charger
  • An external hard drive
  • A power source
  • A blank CD / DVD (recommended if you have an optical disc drive)

Please follow the instructions below for your specific operating system to encrypt your computer. Encryption can be risky if not done right, and it is essential that you follow the instructions carefully. If you have any questions, please contact privacy.matters@ubc.ca.

Stage 1: Check if your computer has already been encrypted

If your computer is already encrypted, don't encrypt again. To check if your computer has already been encrypted, follow the instructions on the UBC IT Knowledge Base.

Stage 2: Back up your computer

Do not encrypt until you have backed up your computer! If you do not back up your computer and issues are encountered during the encryption process, you will risk losing your data.

Stage 3: Enable BitLocker to encrypt your computer

Do not encrypt until you have backed up your computer!

  4. Choose where to save recovery key.
    1. It is highly recommended that you allow Microsoft store your recovery key using your Microsoft Account.
    2. It is recommend that you also save a copy of your recovery key to your personal network storage drive (UBC Home Drive - Vancouver; F: Drive - Okanagan), so that University IT Support Staff can assist you in the event of an incident.

  5. Saving your recovery key is very important. If you do not know your device password and you lose access to your encryption recovery key, there is no way to access your data.

    See the options available to users to store their encryption recovery keys in the Encryption FAQ.
  6. It is recommended that you create a second recovery key and store it in a safe place off of the computer you have encrypted, preferably multiple safe places. See the options available to users to store their encryption recovery keys in the Encryption FAQ.
  7. If turning on BitLocker fails, contact your UBC IT or your local IT Support. You may not have a TPM Chip.
