According to Neowin , since the launch of Windows 11 in 2021, two technological terms, Trusted Platform Module (TPM) and Secure Boot, have become more popular. Initially, they were only required to install a new operating system. However, their importance has now gone beyond that as more and more popular games, such as Call of Duty , require gamers to enable these features to operate anti-cheat software.
Gamers may not be able to enter the game due to two security features.
The problem is that TPM and Secure Boot are low-level features, managed in the computer's BIOS/UEFI rather than in Windows. This leaves many gamers, especially those who are not tech-savvy, confused and unsure of how to enable them.

Gamers cannot run games on Steam without enabling TPM and Secure Boot

Understanding this difficulty, Valve has officially added a checking tool right in Steam. Specifically, in the latest beta update, users can easily access Help > System Information to see if the status of TPM and Secure Boot on their computer has been enabled or not.
While Steam won’t walk you through the steps to enable these two features (as the process can vary depending on your system and motherboard), it’s still a very worthwhile change, as it allows gamers to quickly diagnose their system rather than having to fumble around trying to figure out why their favorite game won’t launch.
Also in a related announcement, Valve confirmed that it will officially stop supporting the 32-bit version of Windows 10 operating system from January 1, 2026. The company recommends that users should upgrade to the 64-bit version of Windows soon to ensure they continue to receive updates and experience the game in the best way.
