How To Use BitLocker on Drives without TPM
BitLocker is an encryption feature available in Ultimate and Enterprise versions of Windows 7 and Vista, but requires a Trusted Platform Module (TPM) on the system. Not all systems include TPM and today we take a look at how to bypass it so you can use BitLocker.
..What happens if you get this goofy error…and what is a TPM anyway? TPM stands for Trusted Platform Module which is a microchip in a computer that supports advanced security features. It’s where BitLocker stores the encryption key. If you have a drive that doesn’t have a compatible TMP then you’ll need to use the following steps and have a flash drive.
..After the restart you’re prompted to use the startup key on the flash drive every time you start the computer.
