Microsoft is requiring the use of TPM 2.0 security modules for Key Management Service (KMS) activation servers to combat unlicensed software and corporate piracy. KMS, used by organizations for mass activation of devices, has been targeted by hackers who create counterfeit servers. The new protocol mandates that KMS hosts validate their hardware credentials through the TPM 2.0 chip before activating client devices. This initiative will mainly affect illegal infrastructures in the corporate sector, while legitimate PC users will not be impacted. Starting in August 2026, Windows Server 2025 will introduce hardware readiness alerts to help system administrators prepare for these changes. TPM 2.0 has been required for Windows 11 since 2021, and its application is being expanded to address vulnerabilities in volume licensing.
