Microsoft's fixed lifecycle policy governs all Windows Server releases, creating predictable 10-year windows for infrastructure planning.
With critical security updates tied to support phases, understanding these deadlines is essential for:
📆 Budgeting hardware/software refresh cycles
🔒 Maintaining compliance standards
🛡️ Preventing security vulnerabilities
☁️ Evaluating cloud migration timelines
