requires PC players tohave TPM 2.0 and Secure Boot enabled. These security features help support TeamRicochet's anti-cheat system and create a safer, fairer environment forplayers.<o:p></o:p>
Most modern PCs already support bothfeatures, but they may not be enabled by default. If you're preparing to playMW4 on PC, it's a good idea to check your system before launch and enableanything missing. If you're also planning to

to level up, unlock rewards, or progressfaster after getting your PC ready, make sure your system meets these securityrequirements first.<o:p></o:p>
This guide explains how to check TPM 2.0 andSecure Boot, how to enable them in your BIOS, and what to do if MW4 stillreports a problem.
<o:p></o:p>
What Are TPM 2.0 andSecure Boot?<o:p></o:p>
TPM 2.0 (Trusted Platform Module) is asecurity technology built into many modern PCs. It provides hardware-basedsecurity functions and can help verify that the system is operating in atrusted state.<o:p></o:p>
Secure Boot is a UEFI security feature thathelps prevent unauthorized software from loading during the PC's startupprocess.<o:p></o:p>
For Modern Warfare 4, both features areimportant parts of the PC security requirements and support the game'santi-cheat protections.<o:p></o:p>
Before changing anything in your BIOS, firstcheck whether they are already enabled.
<o:p></o:p>
1. How to Check if TPM2.0 Is Enabled<o:p></o:p>
You can check your TPM status directly fromWindows without entering the BIOS.<o:p></o:p>
Step 1: Open the TPMManagement Tool<o:p></o:p>
1. Press Windows + R on your keyboard.<o:p></o:p>
2. Type tpm.msc in the Run window.<o:p></o:p>
3. Press Enter.<o:p></o:p>
A TPM Management window will appear.<o:p></o:p>
Step 2: Check the TPMStatus<o:p></o:p>
Look for the status information.<o:p></o:p>
If you see:<o:p></o:p>
• Status: TPM is ready for use<o:p></o:p>
• Specification Version: 2.0<o:p></o:p>
then TPM 2.0 is already enabled and ready.<o:p></o:p>
If Windows reports that a compatible TPMcannot be found, your PC may have TPM disabled in the BIOS.<o:p></o:p>
You can also check TPM through:<o:p></o:p>
Windows Security → Device Security → SecurityProcessor Details<o:p></o:p>
If TPM 2.0 is active there, you generallydon't need to make any additional changes.
<o:p></o:p>
2. How to Check SecureBoot<o:p></o:p>
Next, you'll need to check whether SecureBoot is enabled.<o:p></o:p>
Step 1: Open SystemInformation<o:p></o:p>
1. Press Windows + R.<o:p></o:p>
2. Type msinfo32.<o:p></o:p>
3. Press Enter.<o:p></o:p>
This opens the System Information window.<o:p></o:p>
Step 2: Check BIOS Mode<o:p></o:p>
Find BIOS Mode.<o:p></o:p>
Ideally, it should say: UEFI.<o:p></o:p>
Then find Secure Boot State. ForModern Warfare 4, it should show: On.<o:p></o:p>
If Secure Boot already says On andyour BIOS Mode is UEFI, you should be ready on this side.<o:p></o:p>
What If BIOS Mode SaysLegacy?<o:p></o:p>
Be careful if your system is running in Legacymode.<o:p></o:p>
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.<o:p></o:p>
Changing boot settings without properlypreparing the drive can prevent Windows from starting. Therefore, don't simplyswitch from Legacy to UEFI without checking your drive configuration first.<o:p></o:p>
Before Changing Your BIOSSettings<o:p></o:p>
Changing BIOS settings incorrectly can causeboot problems, so take a few precautions before making changes.<o:p></o:p>
Before proceeding:
<o:p></o:p>
• Save your BitLocker recovery key: Ifyou use BitLocker encryption, ensure you have your recovery key backed up.<o:p></o:p>
• Backup important files: As ageneral precaution, always back up your critical data before making significantsystem changes.<o:p></o:p>
• Only change the specified settings: Restrictyour BIOS modifications to TPM, UEFI, CSM (Compatibility Support Module), andSecure Boot settings as guided. Do not clear, reset, or delete TPM keys.<o:p></o:p>
• Managed PCs: If your PC ismanaged by a school or workplace, some settings may be blocked. Contact your ITadministrator for assistance.<o:p></o:p>
3. How to Enable TPM 2.0in BIOS<o:p></o:p>
If TPM isn't enabled, you'll need to restartyour PC and enter the BIOS/UEFI settings.<o:p></o:p>
One convenient method in Windows is:<o:p></o:p>
Window 11:
Start → Settings → System → Recovery → Nextto Advanced Startup → Restart Now<o:p></o:p>
Window 10:
Start → Settings → Update & Security →Recovery → Under Advanced Startup → Restart Now<o:p></o:p>
After restarting, navigate through:<o:p></o:p>
Troubleshoot → Advanced Options → UEFIFirmware Settings<o:p></o:p>
Find the TPM Setting<o:p></o:p>
Once in BIOS, look for a security-relatedsetting for TPM.<o:p></o:p>
The name can vary depending on yourprocessor:<o:p></o:p>
• On AMD systems, this may be called fTPM.<o:p></o:p>
• On Intel systems, it may be called PTT.<o:p></o:p>
Enable the setting, save your changes,and reboot. After Windows loads, run tpm.msc again or check WindowsSecurity to confirm TPM 2.0 is active.
<o:p></o:p>
4. How to Enable SecureBoot<o:p></o:p>
1. Restart your PC and enter your BIOSsettings.<o:p></o:p>
2. Go tothe Boot or Security tab of your BIOS menu.<o:p></o:p>
3. Enable Secure Boot.<o:p></o:p>
4. If your system is in legacymode, confirm your drive uses GPT before switching to UEFI.You may also need to disable CSM or legacy boot.<o:p></o:p>
5. Save your changes, reboot, and confirm inSystem Information (msinfo32) that Secure Boot is On.<o:p></o:p>
6. Consult your motherboard manual forexact BIOS instructions, as menu layouts can vary between manufacturers.
<o:p></o:p>
5. User Account ControlPrompt<o:p></o:p>
The first time you launch the game, Windowsmay ask for permission to allow enrollaik.exe to make changes to your device.Select Yes if you have administrator access.
<o:p></o:p>
6. Use the Call of DutySecure Attestation Wizard<o:p></o:p>
To further simplify the compliance check,Call of Duty is providing a dedicated Secure Attestation Wizard. This toolwill scan your PC's BIOS information and quickly determine if TPM 2.0 andSecure Boot are ready.<o:p></o:p>
The general process is:<o:p></o:p>
1. Download the Secure Attestation Wizard.<o:p></o:p>
2. Extract the ZIP file.<o:p></o:p>
3. Launch the application.<o:p></o:p>
4. Accept the terms.<o:p></o:p>
5. Run the scan.<o:p></o:p>
6. Grant administrator permission if Windowsrequests it.<o:p></o:p>
If your PC passes the check, no additionalaction should be necessary.<o:p></o:p>
If your system isn't compliant, the wizardcan identify what needs attention and provide guidance for the next steps.
<o:p></o:p>
What If MW4 Still SaysTPM or Secure Boot Is Missing?<o:p></o:p>
If you've enabled both features but ModernWarfare 4 still displays a TPM or Secure Boot warning, try thesetroubleshooting steps.<o:p></o:p>
Update your BIOS to the latest version:
BIOS updates ofteninclude stability improvements and support for new features.<o:p></o:p>
Ensure your OS drive uses GPT:
If you areswitching from legacy to UEFI, your operating system drive must beformatted with the GUID Partition Table (GPT) scheme.<o:p></o:p>
School or work-managed PCs:
If yourorganization manages your PC, some changes might be blocked.<o:p></o:p>
Motherboard manual:
Always refer to yourmotherboard manual for specific and detailed BIOS instructions. <o:p></o:p>
