Installation options[ edit ] Unlike its predecessor, Windows Server can switch between " Server Core " and "Server with a GUI " installation options without a full reinstallation. Server Core — an option with a command-line interface only — is now the recommended configuration. There is also a third installation option that allows some GUI elements such as MMC and Server Manager to run, but without the normal desktop, shell or default programs like File Explorer. In the new Processes tab, the processes are displayed in varying shades of yellow, with darker shades representing heavier resource use. Unlike the Windows 8 version of Task Manager which looks similar , the "Disk" activity graph is not enabled by default.
