Microsoft Windows Server 2025 Standard – 2 Core Add-On License allows organizations to extend existing Windows Server Standard licensing to cover additional processor cores on server hardware.

Because Windows Server uses a core-based licensing model, all physical cores on the server must be properly licensed. The 2-core add-on license provides flexibility to scale licensing as hardware requirements grow.

These licenses are commonly used in combination with the 16-core base license to fully license servers with more than 16 cores.

Key Benefits

Flexible Core Licensing
Add additional core licenses to match server hardware specifications.

Scalable Infrastructure Support
Supports servers with higher core counts.

Licensing Compliance
Ensures all cores running Windows Server are properly licensed.
