How to Encrypt your Sheridan Laptop using Bitlocker

[updated September 21, 2020] Follow the instructions below to encrypt your Sheridan owned or leased Windows laptops using Microsoft BitLocker Administration (MBAM). This will protect data on employee laptops in the event the device is lost or stolen and will have no noticeable impact to your day-to-day activities or your laptop’s performance.
