Core-Based Licensing Explained
Modern Windows Server is licensed by physical CPU cores — you must license every core in the server, with a minimum of 16 cores per server (and 8 per processor). A 16-core licence covers a typical single- or dual-CPU machine; add core packs for higher-density hardware. If you are unsure how many cores you need, contact our team for guidance.
