Bitlocker Encryption for Microsoft Windows

Faculty and staff should contact their IT support staff or ITS for assistance configuring and troubleshooting BitLocker whole disk encryption.

 

Overview

Microsoft Windows provides a method to encrypt storage disks on a computer in order to protect the data against physical theft or loss. This full-disk encryption technology is named BitLocker and it can be used to protect sensitive data stored on local disks. BitLocker protects data when the computer is powered off or hibernating and to a lesser degree when the computer is sleeping.

Requirements

Before enabling Microsoft BitLocker, ensure the computer is logged in with administrative rights. Access to a printer will allow the printing of the recovery key and documentation that encryption was performed. Consider backing up important documents before you begin. Additionally, the device to be encrypted must meet the two requirements below:

  • Operating System
    • Windows 7 Ultimate or Enterprise
    • Windows 8 Professional or Enterprise
    • Windows 10 Professional or Enterprise
  • Trusted Platform Module (TPM) chip

Enable BitLocker

  • First ensure that you have TPM setup and have taken ownership please visit https://technet.microsoft.com/en-us/library/cc754524%28v=ws.11%29.aspx for more information on turning on TPM.
  • Download FVE.zip, a file containing UNC’s BitLocker configuration.
  • Download
  • Extract or open the zipped file. Right-click on the file and ‘Run as administrator’. This will apply the University’s BitLocker configuration.
    Note, it will execute quickly but you may see a black box briefly.

BitLocker Logon

With BitLocker enabled with a PIN, the computer will utilize a different method for startup. When the PC is powered on or restarted, a Microsoft BitLocker prompt will appear and ask for the PIN.

Forgotten PIN

If you have forgotten your PIN, you will need a BitLocker recovery password in order to log in to the computer. You should retrieve the document you printed earlier from the Enabling BitLocker section. If you have lost this document, you will not be able to recover your data. If your computer is managed by Information Technology Services or another University organization, contact that organization for assistance.
