Installing Hyper-V in Server Core
The Server Core installation option is introduced in Windows Server 2012 R2. It creates
an operating system installation without a GUI shell. You can either manage the server
remotely from another system or use the Server Core's command-line interface.
This installation option provides the following benefits:

■

Reduces attack surface (because fewer applications are running on the server)

■

Reduces maintenance and management (because only the required options are
installed)

■

Requires less disk space and produces less processor utilization

■

Provides a minimal parent partition

■

Reduces system resources required by the operating system as well as the attack surface
