What is the Server Core installation option in Windows Server?
Applies to: Windows Server 2019, Windows Server 2016, and Windows Server (Semi-Annual Channel)
The Server Core option is a minimal installation option that is available when you are deploying the Standard or Datacenter edition of Windows Server. Server Core includes most but not all server roles. Server Core has a smaller disk footprint, and therefore a smaller attack surface due to a smaller code base.
Server (Core) vs Server with Desktop Experience
When you install Windows Server, you install only the server roles that you choose - this helps reduce the overall footprint for Windows Server. However, the Server with Desktop Experience installation option still installs many services and other components that are often not needed for a particular usage scenario.
That's where Server Core comes into play: the Server Core installation eliminates any services and other features that are not essential for the support of certain commonly used server roles. For example, a Hyper-V server doesn't need a graphical user interface (GUI), because you can manage virtually all aspects of Hyper-V either from the command line using Windows PowerShell or remotely using the Hyper-V Manager.
The Server Core difference - core capabilities without the frills
When you finish installing Server Core on a system and sign in for the first time, you're in for a bit of a surprise. The main difference between the Server with Desktop Experience installation option and Server Core is that Server Core does not include the following GUI shell packages:
In other words, there is no desktop in Server Core, by design. While maintaining the capabilities required to support traditional business applications and role-based workloads, Server Core does not have a traditional desktop interface. Instead, Server Core is designed to be managed remotely through the command line, PowerShell, or a GUI tool (like RSAT or Windows Admin Center).
In addition to no UI, Server Core also differs from the Server with Desktop Experience in the following ways:
- Server Core does not have any accessibility tools
- No OOBE (out-of-box-experience) for setting up Server Core
- No audio support
The following table shows which applications are available locally on Server Core vs Server with Desktop Experience. Important: In most cases, applications that are listed as "not available" below can be run remotely from a Windows client computer and used to manage your Server Core installation.
