Microsoft Windows (BitLocker)

Encrypting Microsoft Windows

UF recommends using BitLocker encryption on all current versions of Windows that support it. Home Editions of Windows do not support BitLocker, and are not recommended for use at UF. Faculty, staff and students can obtain low or no cost upgrades to Windows through UF’s agreements with Microsoft.

UF owned computers (including those bought with grant or contract funds) must run the UFEM agent, which provides capabilities to manage BitLocker in order to comply with the university Mobile Computing and Storage Devices standard.

BitLocker Encryption

The following directions are for installing BitLocker encryption on Windows 10. UF owned computers (including those bought with grant or contract funds) must run the UFEM agent, which provides capabilities to manage BitLocker in order to comply with the university Mobile Computing and Storage Devices standard.

BitLocker Installation

  1. Begin by opening the Control Panel and selecting BitLocker Drive Encryption.
  2. When the new window opens, click on Turn on BitLocker.Bitlocker Instructions
  3. If you receive a Trusted Platform Module error as pictured below, follow the steps in the section ‘Enabling Additional Authentication Method (no TPM)’ below. If no error, proceed with the next step.Bitlocker Instructions
  4. A new window will pop-up with a green status bar. Once that completes, it will ask how you want to save your recovery key. This recovery key is vitally important, if you forget your password and do not have access to this key, there is no way to access your hard drive or any files stored on it. If you have a Microsoft Account, saving it there is suggested. If you save it to a file, make sure to copy it to a location that is secure, but not on the BitLocker-protected disk. Printing a copy and placing it in a secure location, such as a safety deposit box, is also recommended.Bitlocker Instructions
  5. The next window asks to choose how much of your drive to encrypt. Select Encrypt Entire Drive, then hit Next. Selecting any other option will not be compliant with UF policy.Bitlocker Instructions
  6. The next window asks “Are you ready to encrypt this drive?”. Select Run BitLocker system check and click Continue. Your computer needs to restart now, click Restart Now.
  7. After the computer restarts, it will automatically start encrypting the drive. This can take a few hours up to 12 or more, depending on the size of the hard drive and speed of the computer. You can check the encryption status with the System Tray icon.
  8. While waiting for the encryption, make sure to fill out the Encryption Form for Unsupported Devices.
