Trusted Platform Module (TPM) 2.0 and Secure Boot for Call of Duty

Information about enabling TPM 2.0 and Secure Boot on your PC to play Call of Duty

 

Did you enable TPM 2.0 but keep getting prompted in Call of Duty? It’s possible your motherboard requires a BIOS firmware update. Learn more about updating BIOS firmware.

 

The Trusted Platform Module 2.0 (TPM 2.0) is a technology that provides hardware-based security features on PCs operating Windows.

Secure Boot is another system-level feature that helps protect against low-level cheats by ensuring only trusted software loads during your PC’s startup. Enabling Secure Boot alongside TPM 2.0 provides an added layer of protection and is recommended for the best, most secure Call of Duty® experience.

PC players without TPM 2.0 enabled may receive an in-game notification indicating their system does not meet the new security requirements when launching applicable Call of Duty games.

Both security features were added to Call of Duty with the launch of Season 05, in August 2025.

Both TPM 2.0 and Secure Boot are required to play Call of Duty: Black Ops 7 and Call of Duty: Warzone; however, neither are required to play other currently available Call of Duty titles. Keeping these settings enabled ensures a fair and fun experience for all players

Note: PCs using Windows 11 likely already have both security features enabled, as they are required for the operating system. Windows 10 systems will require updates if TPM is disabled or if a legacy TPM version (1.0 - 1.2) is enabled. While TPM 2.0 requires Windows 10 version 20H2 or later, Call of Duty requires Windows 10 version 22H2 or later.

 

Important! This article offers general guidance, and some steps may differ depending on your PC.

If you’re not familiar with accessing and updating your UEFI/BIOS settings, you should reach out to your hardware manufacturer’s customer support or a professional for assistance. Changing UEFI/BIOS settings improperly can cause system issues, including boot failures.

We also strongly recommend reviewing your PC and motherboard manufacturer’s manuals and support resources before making any changes to your UEFI/BIOS settings. Activision is not responsible for changes made to your UEFI/BIOS settings.

UAC Prompt (enrollaik.exe) Notice

When you first launch Call of Duty: Black Ops 7 or Call of Duty: Warzone, you will receive a Windows User Account Control (UAC) prompt for an application named enrollaik.exe. This is part of the TPM 2.0 registration process. To continue, you must select Yes, which allows us to validate your TPM 2.0 settings. Selecting No will result in not being able to play Call of Duty: Black Ops 7 or Call of Duty: Warzone. This prompt should only occur until you select Yes.

Please note: An issue with AMD firmware 3.*.0.*, where * represents any number, can result in a failure of registration through enrollaik.exe, surfacing the prompt multiple times even if a user selects Yes. If this occurs, it's an indication your PC motherboard BIOS requires an update. Check the Motherboard Guides section for assistance.

 

BIOS Firmware Update Guidance

If you enabled TPM 2.0 and are still getting prompted in Call of Duty, it's possible your motherboard requires a BIOS firmware update. Check your TPM Manufacturer Version to identify if a firmware update is required.

  • Press Windows Key + R to open the Run dialog box.
  • Type tpm.msc and hit Enter.
  • Find your Manufacturer Version under TPM Manufacturer Information (See Figure 9 below).

 

 

Motherboard Guides

To better assist players with activating TPM 2.0 and Secure Boot, below are links to official guides and tutorials from motherboard manufacturers. Links also direct players to official motherboard guides to assist with BIOS/Firmware updates that may be required as part of enabling TPM 2.0 and Secure Boot. If your specific motherboard manufacturer is not listed below, please visit their website directly for guidance and assistance.

Note: Some support materials reference upgrading to Windows 11 as part of its tutorial to TPM 2.0 and Secure Boot. PCs using Windows 11 likely already have both security features enabled, as they are required for the operating system. Windows 10 systems will require updates if TPM is disabled or if a legacy TPM version (1.0 - 1.2) is enabled. While TPM 2.0 requires Windows 10 version 20H2 or later, Call of Duty will require Windows 10 version 22H2 or later.

 

Be sure to consult your motherboard manufacturer's website for the latest information about firmware updates and release notes.
