Windows 8.1 and TPM


  • Can Windows 8 support TPM v1.2? Or it is madantory to have TPM v2 and above?

    Hardware without TPM module can use a "firmware" version of TPM, not sure what is the different betweeen Discrete TPM and Firmware/Software TPM.

    Any advise?

    Thanks in advance for your help.

  • Windows 8 supports TPM 1.2 for Bitlocker, for secure boot TPM must comply with the TCG TPM Main Specification, Version 1.2, Revision 103 (or a later), parts 1, 2 and 3. For more information, see the article  Windows 8 Hardware Certification Requirements.

    The difference between Discrete TPM and Firmware/Software TPM is that a Discrete TPM is a own chip on the motherboard,  a Firmware TPM is integrated on some other components on the motherboard.

    You can use some security features like bitlocker without a TPM but it's not that secure.
