I’ve been using a Bitlocker encrypted drive for a month now and it’s been totally transparent in terms of speed. I’m surprised. I’m also surprised that it was available on my Windows 8.1 (not Pro) OS. Inspired to boost security on my Ultrabook I’ve also enabled secure boot, increased the security level, made sure Defender and Firewall are working and, this is contentious, made sure my login is only via Windows Live account so the password can be changed remotely. Given the reporting and password / device management in the Microsoft Live account though, it seems worth it. Here’s how you can do it too.
