1. Why is Microsoft making Windows Server licensing changes?

▪ The change to core based licensing is one of several steps Microsoft is taking to evolve our server licensing to support hybrid cloud. This change aligns Windows Server 2016 (on-prem), Windows Server (Azure), SQL Server, and System Center. This change to core licensing aligns the servers to a common and consistent licensing denomination that is already a standard measure for capacity across environments.

2. When referring to “core licensing”, what is a “core”?

▪ A “core” refers to a physical core within the CPU. It does not refer to a virtual CPU within a virtual machine, nor a hyper-threaded core. Only physical cores within the physical CPUs should be licensed.

3. Which Windows Server 2016 editions are licensed per core?

▪ Windows Server 2016 Standard and Datacenter editions are licensed per core. Other editions (Essentialsand Storage Server) are still licensed per-processor.

7. If processors (and therefore cores) are disabled from Windows use, do I still need to license the cores?

▪ If the processor is disabled for use by Windows, the cores on that processor do not need to be licensed.

▪ For example, if 2 processors in a 4 processor server (with 8 cores per processor) were disabled and not available for Windows Server use, only 16 cores would need to be licensed. However, disabling hyper threading or disabling cores for specific programs does not relieve the need for a Windows Server license on the physical cores.

8. With Standard Edition, what virtualization rights are included?

▪ Standard edition includes the rights to install two Windows Server virtual machines on the physical serverwhere the license is assigned. This is in addition to the physical host OS that is installed on the hardware.

▪ In this scenario, the physical host OS should only be used to host the virtual machines. It should not beused as an application server, file server, or domain controller.

▪ These virtualization rights are the same regardless of which hypervisor technology is used.

9. Can I install an older version of Windows Server after purchasing Windows Server 2016?

▪ Windows Server 2016 includes rights to install previous versions of Windows Server instead of Windows Server 2016, however, neither Microsoft or Microsoft’s partners are obligated to provide media or keys for these installations.
