Core Licensing Rules Explained
Windows Server follows core-based licensing rules:
- Every physical server requires a minimum base license of 16 Cores.
- All physical cores on the server must be licensed.
- Standard edition permits running 2 virtual machines (VMs) or Hyper-V containers per licensed host.
Upgrade your server infrastructure with an authentic Windows Server 2025 Standard 16-Core Key, or maintain legacy environment compatibility with our verified Windows Server 2022 Standard Key.
