TPM 2.0 Not Detected — Windows 11 Trusted Platform Module Requirement Error

Errorsystem

Overview

Fix TPM 2.0 not detected errors preventing Windows 11 installation or upgrade when the TPM chip is disabled in BIOS or not present on the motherboard.

Key Details

  • Windows 11 requires TPM (Trusted Platform Module) version 2.0 for installation and security features
  • TPM is a hardware security chip on the motherboard that stores encryption keys and handles secure boot
  • Most modern CPUs (Intel 8th gen+, AMD Ryzen 2000+) include firmware TPM (fTPM) built into the processor
  • TPM may be present but disabled in BIOS/UEFI settings, showing as 'not detected' in Windows
  • The error appears during Windows 11 installation, upgrade, or in PC Health Check tool

Common Causes

  • TPM is disabled in BIOS/UEFI settings (common default on many motherboards)
  • Motherboard does not have a discrete TPM chip and CPU does not support firmware TPM
  • TPM firmware needs updating to reach version 2.0 (older systems may have TPM 1.2)
  • Secure Boot is disabled, which is also required alongside TPM 2.0 for Windows 11

Steps

  1. 1Check current TPM status: press Win+R, type tpm.msc, and check the TPM version and status
  2. 2Enable TPM in BIOS: restart, enter BIOS (Del/F2), find Security > TPM/fTPM/PTT and enable it
  3. 3For Intel CPUs: enable 'Intel Platform Trust Technology (PTT)' in BIOS security settings
  4. 4For AMD CPUs: enable 'AMD fTPM' or 'AMD PSP fTPM' in BIOS security settings
  5. 5Also enable Secure Boot in BIOS under Boot settings, as Windows 11 requires both TPM 2.0 and Secure Boot

Frequently Asked Questions

Microsoft officially requires TPM 2.0, but registry hacks can bypass the check. However, bypassing may prevent future updates and is not recommended for security-sensitive systems.
