Server Core App Compatibility Feature on Demand
Server Core App Compatibility Feature on Demand (FOD) significantly improves the app compatibility by including a subset of binaries and components from Windows Server with the Desktop Experience. Server Core is kept it as lean as possible by not adding the Windows Server Desktop Experience graphical environment itself, increasing the functionality and compatibility.
This optional feature on demand is available on a separate ISO and can be added to Windows Server Core installations and images only, using DISM.
Windows Deployment Services (WDS) Transport Server role added to Server Core
Transport Server contains only the core networking parts of WDS. You can now use Server Core with the Transport Server role to create multicast namespaces that transmit data (including operating system images) from a standalone server. You can also use it if you want to have a PXE server that allows clients to PXE boot and download your own custom setup application.
