The Windows Server 2025 Datacenter 16 Core License covers the standard minimum licensing for a single physical server: 16 cores, or two 8-core processors. It is the usual starting point for a virtualization host that runs many Windows Server virtual machines.
Best For
A single two-processor host with 8 cores per CPU
Virtualization hosts where you plan to run many VMs
Businesses replacing or consolidating older servers
What You Get
16 Windows Server 2025 Datacenter core licenses
Rights to run unlimited Windows Server virtual machines on the licensed host
Access to Datacenter features such as Storage Replica and Software-Defined Networking
Good to Know
Windows Server is licensed per physical core, with a minimum of 16 cores per server
If your server has more than 16 cores, add 8 Core Packs to cover the rest
CALs are required for users or devices that connect, and are sold separately
Is 16 cores enough for my server?
Count every physical core in the host. If the total is 16 or fewer, this license covers it. If it is higher, add core packs for the difference.
