Windows Server 2025 Standard ? Core Add-on (2 Core) License

With the core-based licensing model of Windows Server 2025, scaling server resources becomes more flexible and more precise. The 2-core add-on license enables targeted expansion of existing Windows Server 2025 Standard installations and ensures that even complex workloads can be run performantly and in compliance with regulations.

Licensing as needed

Windows Server 2025 Standard requires licensing of at least 16 cores per physical server and at least 8 cores per physical processor. With this 2-core license, additional cores can be added in increments of two to cover increased performance requirements or hardware upgrades. The add-on license is particularly relevant for scenarios with growing virtualization needs or increased utilization in data centers.

Integration into modern IT environments

The extension license integrates seamlessly into existing Windows Server 2025 environments ? whether on-premises, hybrid or fully cloud-based. In combination with new features such as hotpatching, GPU partitioning or SMB over QUIC, the server landscape can be operated not only more efficiently, but also more securely and with higher availability.
