HOW TO ENABLE TPM 2.0

Follow these steps on the Windows 11 PC to check and enable TPM 2.0 and Secure Boot so games like COD can run:

1. Check if TPM is already on
   1. Select Start → Settings → Update & Security → Windows Security → Device security.
   2. Look for Security processor.
      • If it is there, select Security processor details.
      • Check Specification version. If it shows 2.0, TPM 2.0 is already enabled.
      • If it shows less than 2.0, the device does not meet Windows 11 / game requirements.
      • If Security processor is missing, TPM may be turned off in firmware (BIOS/UEFI).
2. Second way to check TPM
   1. Press Windows key + R.
   2. Type tpm.msc and select OK.
   3. If it says “TPM is ready for use”, look at Specification Version under TPM Manufacturer Information and confirm it is 2.0.
   4. If it says “Compatible TPM cannot be found”, TPM is disabled in BIOS/UEFI or not present.
3. Enable TPM 2.0 in BIOS/UEFI (if disabled)
   • Restart the PC and enter the BIOS/UEFI setup (key is often Del, F2, F10, or Esc right after turning the PC on).
   • In BIOS/UEFI, look for a setting named TPM, fTPM, PTT, or Security device under Security, Advanced, or Boot menus.
   • Set TPM to Enabled.
   • Save changes and exit (usually F10).
   • Back in Windows, repeat step 1 or 2 to confirm Specification version = 2.0.
4. Check Secure Boot status
   1. Press Windows key, type System Information, and open it.
   2. In the right pane, find Secure Boot State.
      • If it says On, Secure Boot is already enabled.
      • If it says Off, it must be turned on in BIOS/UEFI.
5. Enable Secure Boot in BIOS/UEFI
   • Restart and enter BIOS/UEFI again.
   • Make sure the system is using UEFI (not Legacy/CSM) and the system drive is GPT (the game error suggests this is already OK on a Windows 11 rig).
   • Find Secure Boot under Boot or Security.
   • Set Secure Boot to Enabled (or Windows UEFI mode if that option exists).
   • Save and exit.
   • Boot back into Windows and re-check Secure Boot State in System Information.

If TPM 2.0 and Secure Boot both show as enabled and the game still complains, restart the PC once more and try launching the game again so it can re-check the security settings.
