Encryption: How to manually activate Bitlocker on your Windows machine

Your Windows computer comes bundled with native BitLocker encryption software. OIT recommends that you enable BitLocker with assistance from your SCAD/DCS member or OIT Desktop Support.

OIT offers a centrally managed Princeton Encryption Service that will validate BitLocker on your computer and store the encryption recovery key in an OIT system. If you forgot your password, you can retrieve the recovery key through OIT technical support. Contact your SCAD/DCS member or OIT Help Desk at 8-4357(HELP) option #1 for more information and to enroll your computer into this service. If you decide to participate, you do not need to proceed any further with the below instructions.

BitLocker Drive Encryption is a native security feature that is available in some versions of Windows. It is a whole disk encryption solution; it encrypts everything on which Windows is installed.

To use BitLocker, your computer must satisfy certain requirements. Contact the OIT Help Desk at 8-4357(HELP) option #1 if your computer does not meet one or more of these requirements.
