What is BitLocker in Windows 10
Similar to previous versions, pro and enterprise edition of Windows 10 includes the BitLocker Drive Encryption feature that allows you to use encryption on your PC’s hard drive and on removable drives to prevent prying eyes from snooping into your sensitive data. BitLocker uses an AES encryption algorithm with a 128-bit key or 256-bit key to encrypt disk volumes.
Important Things To Remember
Before learning the steps to encrypt data using BitLocker, you need to remember a few things –
- This feature is only available for Windows 10 Pro or Enterprise.
- To get high-quality results to link yours with Trusted Platform Module (TPM) chip. This is a special microchip that enables your device to support advanced security features.
- It can be used without a TPM chip, but it might need extra authentication steps.
- Your computer’s BIOS must support TPM or USB devices.
- Two partitions must be present on your computer containing the necessary files to start Windows and the partition with the operating system.

Is BitLocker hardware- or software encryption?
The simple answer is BitLocker supports both hardware and software encryption methods. If it can use a hardware TPM and you choose to encrypt the entire drive then it should use hardware encryption.
If you opt to just encrypt a volume on a disk (i.e. one of several partitions) then it will use software encryption. You can also choose to use software encryption if your computer doesn’t meet BitLocker’s requirements.
Check your device has a TPM chip
Foremost, before learning the steps of encryption, you need to make sure that your device has a TPM chip or not. To do that, you have to –

Some of the devices such as Surface Pro 3, Surface Pro 4, or Surface Book comes with preinstalled TPM chip.
Well if you have noticed TPM chip present on your device but still getting error “This Device Can’t use a Trusted Platform Module” while enabling BitLocker on Windows 10. That cause Enter the BIOS or UEFI and look for a TPM setting and ensure it is switched on.
Turn on BitLocker without TPM
Well If your computer doesn’t include a Trusted Platform Module chip, you won’t be able to turn on BitLocker on Windows 10. You get an error message “This Device Can’t use a Trusted Platform Module”. In such a situation you need to use the Local Group Policy Editor to enable additional authentication at startup.
