To use the BitLocker function, you need a computer that has a Trusted Platform Module (TPM). If you try to enable BitLocker on a PC without a TPM, you’ll be told your administrator must set a system policy option.
On the other hand, BitLocker is available only on Professional, Enterprise, and Education editions of Windows. That means if your PC equips with a TPM 1.2 or later; still, you can’t use BitLocker because you will not find an option for BitLocker to configure.
BitLocker typically requires a Trusted Platform Module (TPM 1.2 or later) chip on your computer’s motherboard. This TPM chip generates and stores the actual encryption keys and automatically unlocks your PC’s drive so that when you boot, you can sign in just by typing your Windows login password.
If someone gets physical access to your PC, removes the drive from the computer, and attempts to decrypt it, they will fail to access that without the key stored in the TPM. The TPM won’t work if you change the PC’s motherboard, either.
However, if your motherboard (or laptop) doesn’t have a TPM, you may want to use BitLocker without a TPM, but this will be less secure. But it is always better than nothing.
