Call of Duty: Modern Warfare 4 (COD23) - Detailed Guide for Secure Boot, TPM 2.0 Verification, and Activision Account Setup

Summary

The beta test for Call of Duty: Modern Warfare 4 has officially started preloading! To jump straight into the game once the servers go live, players need to complete several preparations: redeeming the test key, linking an Activision account, enabling Secure Boot and TPM 2.0 in BIOS, and more. This guide provides a complete step-by-step walkthrough. Due to the large size of the beta preload files, direct connections to Steam from some regions often suffer from download throttling, stuck preloads, or interrupted updates. It is recommended to use a game accelerator (like Xunyou) for Call of Duty: Modern Warfare 4 to improve download speed and stability before launching Steam. After acceleration, players can also avoid page timeouts and redemption failures. Additionally, enabling Secure Boot and TPM 2.0 in BIOS is a mandatory requirement for the game to run, and linking an Activision account is essential for redeeming the beta access. These preparations are particularly critical for PC players and directly impact the beta experience. With preloading now available and the beta launch imminent, following this guide ensures players can enter the game smoothly at release time. For the industry, this highlights a growing trend of AAA titles relying on PC hardware security features such as TPM 2.0, which may shape future system requirements.
