Windows 11 TPM Requirement

Your computer will need a Trusted Platform Module (TPM) version 2.0 to run Windows 11. This document describes how to identify what version TPM your computer has.

Steps to Check Your TPM Version

  1. Windows Key + R to bring up the Run dialog.
  2. Then type: tpm.msc and press the Enter (Return) key.
  3. Your TPM version information will show in the information window.

NOTE: Instead of pressing the Windows Key + R in step one above, you can click on the Start Menu and type the word command to find the RUN option.

About the TPM Requirement

Computers that are a few years old may not have the TPM 2.0 version. The 1.2 version is more common for older computers, and some don’t have the TPM at all.

If your motherboard has a port for TPM installation, you could purchase one. With increased demand, the cost may be $50 to $100 or more.

Some CPUs have the ability to emulate TPM, and through a BIOS update they can be upgraded to the 2.0 version.
