Cyber Security Matters. Spread the Word.

Many computer owners face a common problem. Their PC can’t run Windows 11 because of TPM requirements. Microsoft introduced strict hardware requirements for its newest operating system. The Trusted Platform Module (TPM) stands as the main barrier for many users.

This guide helps IT security professionals understand TPM requirements. You’ll learn practical solutions to overcome compatibility issues. We’ll explore both official methods and alternative approaches to install Windows 11.

Our team has tested these methods during server build review processes. The strategies work for most systems with TPM limitations.

Understanding TPM and Windows 11 Requirements

What is TPM?

TPM is a security chip that protects your computer. The chip stores encryption keys and authentication data. It helps prevent unauthorised access to your system.

The module exists as either a physical chip or firmware implementation. Most computers built after 2016 include TPM 2.0 capability. Older systems might have TPM 1.2 or no TPM at all.

Microsoft requires TPM 2.0 for Windows 11 installation otherwise your PC Can’t Run Windows 11. This requirement aims to improve system security across all devices.

Windows 11 System Requirements

Windows 11 has several hardware requirements beyond TPM. Understanding these helps determine your upgrade options.

Minimum System Requirements:

Component Requirement
Processor 1 GHz or faster with 2+ cores on a compatible 64-bit processor
RAM 4 GB
Storage 64 GB
System firmware UEFI, Secure Boot capable
TPM Trusted Platform Module version 2.0
Graphics card DirectX 12 compatible with WDDM 2.0 driver
Display 720p display larger than 9″ diagonally
Internet Windows 11 Home requires internet connectivity

These requirements exceed those of Windows 10. The TPM 2.0 requirement causes the most compatibility problems.

Why Microsoft Mandates TPM for Windows 11

Microsoft implemented the TPM requirement to enhance security. Modern cyber threats require stronger protection measures. TPM helps guard against various attacks.

The module enables hardware-based security features. These include BitLocker encryption and Windows Hello authentication. TPM also supports secure boot processes and verifies system integrity.

During our network penetration testing services, we’ve seen TPM prevent credential theft. The chip stores sensitive data away from the main processor.

How to Check If Your PC Has TPM

Before attempting solutions, you need to verify your TPM status. Several methods can confirm if your computer has TPM capability.

Method 1: Using the TPM Management Console

The TPM Management Console shows detailed information about your TPM.

Step-by-step process:

  1. Press Win + R to open the Run dialog
  2. Type tpm.msc and press Enter
  3. Review the TPM status information

If TPM is present and active, you’ll see its version and status. If not, you’ll receive an error message.

Method 2: Using Device Manager

Device Manager can reveal if your computer has TPM hardware.

  1. Right-click the Start button and select Device Manager
  2. Expand “Security devices”
  3. Look for “Trusted Platform Module”

The presence of this entry indicates TPM hardware exists.

Method 3: Using the System Information Tool

The System Information tool provides comprehensive system details.

  1. Press Win + R and type msinfo32
  2. Press Enter to launch System Information
  3. Look for TPM information under “System Summary”

This method shows both TPM version and status.

Method 4: Using PowerShell

PowerShell offers a command-line approach to check TPM status.

In PowerShell type the following:
Get-TPM

This command displays detailed TPM information. Check the “TpmPresent” and “TpmReady” values.

Method 5: Using Windows 11 PC Health Check App

Microsoft provides an official tool to check Windows 11 compatibility.

  1. Download the PC Health Check app from Microsoft’s website
  2. Install and run the application
  3. Click “Check now” to perform the compatibility check

The tool identifies all compatibility issues, including TPM problems.

Solutions for PCs Without TPM 2.0

If your PC can’t run Windows 11 due to TPM requirements, you have several options. These range from hardware upgrades to registry modifications.

Solution 1: BIOS Update and TPM Activation

Many computers have TPM capability but need activation.

  1. Check your computer manufacturer’s website for BIOS updates
  2. Download and install the latest BIOS version
  3. Restart and enter BIOS settings (typically by pressing F2, F12, or Del)
  4. Look for TPM, Security Chip, or PTT (Intel Platform Trust Technology) settings
  5. Enable the TPM/Security Chip option
  6. Save settings and exit BIOS

After restarting, check if Windows now recognises TPM 2.0.

Solution 2: Add a TPM Module

Some motherboards support adding a physical TPM module.

  1. Check your motherboard manual for TPM header compatibility
  2. Purchase a compatible TPM module (usually around £15-30)
  3. Power down your computer completely
  4. Install the TPM module on the designated header
  5. Boot into BIOS and enable TPM functionality
  6. Save settings and restart

This solution works for many desktop computers with appropriate headers.

Solution 3: Bypass TPM Requirement Using Registry Edit

Microsoft provides a registry modification to bypass TPM checks. This method is unsupported but effective.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup]
"AllowUpgradesWithUnsupportedTPMOrCPU"=dword:00000001

Save this as bypass-tpm.reg and run it before attempting installation.

Alternatively, follow these manual steps:

  1. Press Win + R and type regedit
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
  3. Create a new DWORD value named AllowUpgradesWithUnsupportedTPMOrCPU
  4. Set the value to 1
  5. Close Registry Editor and attempt installation

This method allows installation but may affect future updates.

Solution 4: Clean Installation with Bypass Script

For a clean installation, you can use the Rufus tool with TPM bypass.

  1. Download Rufus from the official website
  2. Insert a USB drive (8GB or larger)
  3. Launch Rufus and select your USB drive
  4. Choose a Windows 11 ISO file
  5. Select “Yes” when prompted to bypass TPM check
  6. Complete the USB creation process
  7. Boot from the USB and follow installation instructions

This creates a modified installation media that skips hardware checks.

Solution 5: Using Windows 11 Enterprise Evaluation

The Enterprise evaluation version offers more flexible requirements.

  1. Download Windows 11 Enterprise evaluation from Microsoft
  2. Create installation media using the Media Creation Tool
  3. Perform a clean installation
  4. Use the same bypass registry edit if needed

This provides a 90-day trial but can be renewed multiple times.

Assessing the Risks of Bypassing TPM Requirements

Bypassing TPM requirements carries security implications. IT security professionals should understand these risks even if your PC can’t run Windows 11.

Security Implications of TPM Bypass

Running Windows 11 without TPM 2.0 reduces system security. You lose several protection mechanisms:

  1. BitLocker may function with reduced security
  2. Windows Hello security features may be limited
  3. Some zero-day attack protections won’t function
  4. Credential Guard may be unavailable

During our work with penetration testing companies, we’ve observed higher vulnerability rates in systems without TPM.

When Bypassing Makes Sense

Despite risks, bypassing may be appropriate in certain scenarios:

  • Testing and development environments
  • Temporary installations for compatibility testing
  • Systems with compensating security controls
  • Hardware that cannot be upgraded but requires Windows 11

Always conduct a risk assessment before bypassing security requirements.
