Windows Server 2016 and System Center 2016 Licensing Update
With the upcoming launch of Windows Server 2016 and System Center 2016, for servers the licensing of Datacenter and Standard Edition will transition from processor licensing to physical core licensing. However, for UC customers, per processor licenses are also available for this 17/18 enrollment term only. Whichever works out better (more economical) for you will depend on your actual server configurations. For client computers, per user or per device based Windows Server CALs and System Center CMLs will continue to be a requirement.
