Another proviso for using this is that systems must have a Trusted Platform Module (TPM), a chip on the motherboard that can securely store and generate encryption keys.
As part of recent tests for a review of Dell's OptiPlex 745 desktop, I installed Windows Vista RC2 to see how it performed. The OptiPlex also includes a TPM, so it seemed like a good opportunity to try out BitLocker.
The first obstacle to tackle was that Dell ships its systems with the TPM disabled by default, so I had to access the Bios setup and enable the chip. This is a two-part process on the OptiPlex; first you have to turn 'TPM Security' on, and then use a second menu option to activate the TPM.
Perhaps foolishly, I thought that Vista might then guide me through the rest of the process. I found the BitLocker option in the Security section of the Windows Control Panel and opened it, to be greeted with a message that helpfully stated 'Your system is not configured to use BitLocker drive encryption'.
Following a little background research, I returned to the system and sought out the new TPM Services module in the Microsoft Management Console. This has facilities to let you initialise a TPM and take ownership, which basically means setting a password to control the TPM. Windows can automatically create a strong password for you and save it to a file on a USB Flash disk, which I duly did.
Sadly, trying BitLocker again simply resulted in a message stating that the Bios was not correctly communicating with the TPM, and recommending that I contact the manufacturer to get an upgrade. Requests to Dell for help have so far not elicited any response, so BitLocker tests will have to wait for another day.
