Call of Duty Modern Warfare 4 requires PC players to have TPM 2.0 and Secure Boot enabled. These security features help support Team Ricochet's anti-cheat system and create a safer, fairer environment for players.
Most modern PCs already support both features, but they may not be enabled by default. If you're preparing to play MW4 on PC, it's a good idea to check your system before launch and enable anything missing. If you're also planning to use CoD MW4 boost to level up, unlock rewards, or progress faster after getting your PC ready, make sure your system meets these security requirements first.
This guide explains how to check TPM 2.0 and Secure Boot, how to enable them in your BIOS, and what to do if MW4 still reports a problem.
What Are TPM 2.0 and Secure Boot?
TPM 2.0 (Trusted Platform Module) is a security technology built into many modern PCs. It provides hardware-based security functions and can help verify that the system is operating in a trusted state.
Secure Boot is a UEFI security feature that helps prevent unauthorized software from loading during the PC's startup process.
For Modern Warfare 4, both features are important parts of the PC security requirements and support the game's anti-cheat protections.
Before changing anything in your BIOS, first check whether they are already enabled.
1. How to Check if TPM 2.0 Is Enabled
You can check your TPM status directly from Windows without entering the BIOS.
Step 1: Open the TPM Management Tool
1. Press Windows + R on your keyboard.
2. Type tpm.msc in the Run window.
3. Press Enter.
A TPM Management window will appear.
Step 2: Check the TPM Status
Look for the status information.
If you see:
• Status: TPM is ready for use
• Specification Version: 2.0
then TPM 2.0 is already enabled and ready.
If Windows reports that a compatible TPM cannot be found, your PC may have TPM disabled in the BIOS.
You can also check TPM through:
Windows Security → Device Security → Security Processor Details
If TPM 2.0 is active there, you generally don't need to make any additional changes.
2. How to Check Secure Boot
Next, you'll need to check whether Secure Boot is enabled.
Step 1: Open System Information
1. Press Windows + R.
2. Type msinfo32.
3. Press Enter.
This opens the System Information window.
Step 2: Check BIOS Mode
Find BIOS Mode.
Ideally, it should say: UEFI.
Then find Secure Boot State. For Modern Warfare 4, it should show: On.
If Secure Boot already says On and your BIOS Mode is UEFI, you should be ready on this side.
What If BIOS Mode Says Legacy?
Be careful if your system is running in Legacy mode.
Before switching from Legacy to UEFI, check whether your Windows system drive uses the GPT partition format. Some systems using Legacy BIOS may still use the older MBR format.
Changing boot settings without properly preparing the drive can prevent Windows from starting. Therefore, don't simply switch from Legacy to UEFI without checking your drive configuration first.
Before Changing Your BIOS Settings
Changing BIOS settings incorrectly can cause boot problems, so take a few precautions before making changes.
Before proceeding:
• Save your BitLocker recovery key: If you use BitLocker encryption, ensure you have your recovery key backed up.
• Backup important files: As a general precaution, always back up your critical data before making significant system changes.
• Only change the specified settings: Restrict your BIOS modifications to TPM, UEFI, CSM (Compatibility Support Module), and Secure Boot settings as guided. Do not clear, reset, or delete TPM keys.
• Managed PCs: If your PC is managed by a school or workplace, some settings may be blocked. Contact your IT administrator for assistance.
3. How to Enable TPM 2.0 in BIOS
If TPM isn't enabled, you'll need to restart your PC and enter the BIOS/UEFI settings.
One convenient method in Windows is:
Window 11: Start → Settings → System → Recovery → Next to Advanced Startup → Restart Now
Window 10: Start → Settings → Update & Security → Recovery → Under Advanced Startup → Restart Now
After restarting, navigate through:
Troubleshoot → Advanced Options → UEFI Firmware Settings
Find the TPM Setting
Once in BIOS, look for a security-related setting for TPM.
The name can vary depending on your processor:
• On AMD systems, this may be called fTPM.
• On Intel systems, it may be called PTT.
Enable the setting, save your changes, and reboot. After Windows loads, run tpm.msc again or check Windows Security to confirm TPM 2.0 is active.
4. How to Enable Secure Boot
1. Restart your PC and enter your BIOS settings.
2. Go to the Boot or Security tab of your BIOS menu.
3. Enable Secure Boot.
4. If your system is in legacy mode, confirm your drive uses GPT before switching to UEFI. You may also need to disable CSM or legacy boot.
5. Save your changes, reboot, and confirm in System Information (msinfo32) that Secure Boot is On.
6. Consult your motherboard manual for exact BIOS instructions, as menu layouts can vary between manufacturers.
5. User Account Control Prompt
The first time you launch the game, Windows may ask for permission to allow enrollaik.exe to make changes to your device. Select Yes if you have administrator access.
6. Use the Call of Duty Secure Attestation Wizard
To further simplify the compliance check, Call of Duty is providing a dedicated Secure Attestation Wizard. This tool will scan your PC's BIOS information and quickly determine if TPM 2.0 and Secure Boot are ready.
The general process is:
1. Download the Secure Attestation Wizard.
2. Extract the ZIP file.
3. Launch the application.
4. Accept the terms.
5. Run the scan.
6. Grant administrator permission if Windows requests it.
If your PC passes the check, no additional action should be necessary.
If your system isn't compliant, the wizard can identify what needs attention and provide guidance for the next steps.
What If MW4 Still Says TPM or Secure Boot Is Missing?
If you've enabled both features but Modern Warfare 4 still displays a TPM or Secure Boot warning, try these troubleshooting steps.
Update your BIOS to the latest version: BIOS updates often include stability improvements and support for new features.
Ensure your OS drive uses GPT: If you are switching from legacy to UEFI, your operating system drive must be formatted with the GUID Partition Table (GPT) scheme.
School or work-managed PCs: If your organization manages your PC, some changes might be blocked.
Motherboard manual: Always refer to your motherboard manual for specific and detailed BIOS instructions.
