Server Manager is a management console in Windows Server that helps IT professionals provision and manage both local and remote Windows-based servers from their desktops.
Server Manager is installed by default with all editions of Windows Server and can be used to manage server core options. The Server Manager was first introduced with Windows Server 2008 and it gave administrators the ability to install, configure and manage server roles and features and since then, it has become the central control point for the administration of Windows Server.
