Nano Server is a headless, remotely managed version of its server product that comes as a separate installation option in Windows Server 2016, which is in Technical Preview 5 at the moment, but is thought to represent the final feature version before RTM.
One of the main benefits of the product is that the disk and processing requirements for Nano Server are much less than a full-size Windows Server installation. But before installing one should seriously consider the following fact (stated by Microsoft recently): “Group Policy and the associated Group Policy Management Console (GPMC), editor (GPMC), Group Policy client and local policy editor (GPEdit) tools are not present on Nano Server. Even when domain joined, Nano Server will not consume and enact Group Policy settings.”
So, if you want to upgrade older Windows Server version and still utilize Group Policy, Windows Server 2016 and Windows 10 clients continue to have full support for Group Policy.
