Windows Server 2025 is Microsoft's latest server operating system, bringing new features and enterprise-focused improvements. Discussions on WindowsForum.com cover a range of topics including missing Windows Security app after clean installation, security vulnerabilities like CVE-2025-33073 bypassing SYSTEM shell mitigations, and fixes for WUSA .msu network share bugs in Patch Tuesday updates. Enterprise adoption is highlighted by AWS automated in-place upgrades from Windows Server 2016, support for DNS over HTTPS for encrypted resolution, and performance benchmarks showing AMD EPYC processors delivering up to 3x OLTP throughput.
