The Microsoft Management Console (MMC) is a component of Windows that provides an administrative interface for system configuration. It can be extended with _snap-ins_, which are COM or managed code components that provide the user interface for a particular administrative domain.
The Microsoft Management Console (MMC) is a Windows application used by administrators and power users to administer a Windows system. Administration of varying domains -- such as event logs or starting and stopping [Windows service]s -- can be done within the same console.
MMC hosts components called snap-ins. These are implemented Snap-ins are extensions to the MMC executable, which hosts them and provides a window frame into which they expose their user interfaces. Traditionally, snap-ins have been implemented as COM components, but in recent releases of Windows, support is provided for snap-ins written for the managed runtime.
