Call of Duty: Modern Warfare 4 will require TPM 2.0 and Secure Boot on PC. During the beta, a computer that fails Activision’s security checks may be unable to access any online mode.
This is not a rumor or an unofficial leak. Activision has published the requirements through its official support pages as part of the company’s expanding RICOCHET Anti Cheat protection.
What PC players need
Activision says compatible computers must use Windows 10 version 22H2 or later, or Windows 11. The system must also support UEFI, TPM 2.0, Secure Boot and a GPT formatted system drive.
Many relatively modern computers already support these features. Activision lists Intel 8th Generation processors and newer, along with AMD Ryzen 2000 series processors and newer, as common examples of compatible hardware.
Players can use the official Call of Duty Secure Attestation Wizard to check whether their computer passes the required security tests.
Why Activision is adding these checks
TPM 2.0 and Secure Boot allow RICOCHET to verify that the computer started through a trusted environment. This makes it more difficult for certain cheats to hide at a very low system level before the game launches.
Activision says the RICOCHET kernel level driver only operates while a protected Call of Duty title is running.
This protection is not completely new. TPM 2.0 and Secure Boot are already being used with Black Ops 7 and Warzone. Modern Warfare 4 continues the same approach and may prevent noncompliant computers from accessing online gameplay.
What players are saying
Community reaction on Reddit is divided.
Some players welcome stronger hardware based protection and believe every additional barrier can make cheating more difficult. Others report failed attestation warnings even when TPM 2.0 and Secure Boot appear to be enabled correctly.
Several users also describe confusing BIOS settings, firmware warnings and concerns involving BitLocker recovery keys. These are individual reports and should not be treated as official instructions.
Activision warns that incorrect BIOS changes can prevent a computer from starting. Players should use the official verification tool and follow instructions from their motherboard manufacturer instead of copying random BIOS fixes from social media.
The new requirement could strengthen Call of Duty’s defenses, but the beta will also test whether Activision can make the verification process reliable for legitimate players.
