Microsoft Tightens Corporate Windows Activation with TPM-Bound KMS Servers
Microsoft is strengthening its corporate Windows licensing controls by introducing new requirements for KMS servers used in volume activation. The changes will bind KMS hosts to TPM hardware attestation, preventing cloned or fake servers from issuing licenses to unlicensed devices. Warnings will begin appearing in Windows Server 2025 in August 2026, with mandatory enforcement planned for the next LTSC release. Existing KMS systems will continue operating normally until the new rules take effect. The update targets enterprise environments with on-premises KMS infrastructure and does not affect individual consumer devices or common non-KMS activation bypass methods. Administrators can already verify TPM support on physical servers using the Get-TpmSupportedFeature command.
