About this tag
Windows Server 2025 discussions on WindowsForum.com center on enterprise administration, security, and activation changes. Recent threads highlight Microsoft's introduction of TPM-backed attestation readiness checks for KMS hosts, a step toward the future KMS Hardware-Secured model that will require hardware-verified trust in the next LTSC release. Administrators are advised to inventory existing KMS infrastructure rather than migrate immediately. Additional coverage includes automated DISA STIG drift assessments for Windows Server 2025 in cloud security platforms, useful for federal and enterprise compliance teams. The tag also touches on broader Windows update cycles, where server-management improvements appear alongside Windows 11 patches, emphasizing the need to separate deployment mechanisms and timetables.
