About this tag
Windows Server 2025 is Microsoft's latest Long-Term Servicing Channel server platform, released November 1, 2024. Discussions on WindowsForum.com cover upcoming KMS TPM readiness checks for hardware-secured activation, security updates, and lifecycle planning. Administrators can evaluate the OS via a 180-day Evaluation Center ISO. Topics include RDP file signing with rdpsign /sha256, a July 2026 update (KB5099536) with potential MegaRAID CacheCade issues, and CVE-2026-58542, a Windows Media RCE vulnerability patched in July 2026. The tag also addresses migration timing from Windows Server 2022, whose mainstream support ends October 13, 2026, with extended support through 2031.
