TPM stands for Trusted Platform Module. TPM is a microcircuit (or chip) designed to provide basic security-related functions, mainly involving encryption keys. TPM comes preinstalled on the motherboard of a desktop or laptop computer and communicates with the rest of the system using a hardware bus.
TPM currently has 2 versions: TPM 1.2 and TPM 2.0. TPM 2.0 is a newer security standard that includes the functions of TPM 1.2 and adds more algorithms and more trusted keys, with broader support for applications.
Step 1: Press Windows + R to open the Run dialog box. Type tpm.msc and click OK.
Step 2: In the TPM Manufacturer Information screen, check the Specification Version value. It must be 2.0, as in the screenshot below.
If you don’t see it, or you get an error saying no compatible TPM was found, then the TPM chip is not on your motherboard or is actually disabled in the BIOS.
