What is a TPM? Everything you need to know about Trusted Platform Module

The launch of Windows 11 last year really put TPMs in the spotlight, with many people wondering if their PC was up to it. But what is TPM and why is it important?

Read on to find out what a TPM chip is and why Microsoft insists so much on including it.

What is a TPM chip?

A TPM (also known as a Trusted Platform Module chip) is a cryptoprocessor that secures a computer via an embedded cryptographic key. The main function of a TPM is to prevent hackers from gaining access to your computer and disclosing your data, which makes it an important aspect of your PC’s security system.

You will need a TPM chip to run Windows 11 effectively as Microsoft puts more emphasis on security and safety of its platforms.

How does a TPM work?

A TPM is usually either built into a device’s motherboard or manually added to the CPU. Companies like AMD and Intel have ensured that all modern processors incorporate this technology, however, anyone using a PC a few years ago may miss this feature.

Each time you log on to your computer, the TPM provides a unique code called a cryptographic key. If there is no problem detected, the PC or laptop will start normally, but if the PC considers that your security is compromised, it will automatically enter a lock to prevent hackers from accessing it.

Does my device have a TPM chip?

You can check if your laptop or PC has a TMP chip using a few methods, the first being checking the Windows built-in TPM management tool.

Just press Windows + R at the same time to open a dialog window. Type tpm.msc in the box and press Enter.

If your device shows a window about the TPM inside your PC, you will have a TPM. The bottom right corner will tell you which version as Windows 11 needs the TPM 2.0 option to work.

If a “Compatible TPM not found” message appears, your PC does not have a TPM chip.

But don’t lose hope; If your system is reported as having no TPM, despite using a modern CPU, you may just need to enable it in your BIOS.

For example, our system was reported to have no TPM despite using a Ryzen 7 5800X CPU, which is on the approved CPU list.
