What is mmcshext.dll?

Part of MMC Shell Extension DLL by Microsoft

What is it?

Microsoft Management Console (MMC) is an extensible common presentation service for management applications. MMC provides a common host environment for snap-ins, provided by Microsoft and third party software vendors. Snap-ins provide the actual management behavior; MMC itself does not provide any management functionality. The MMC environment provides for seamless integration between snap-ins.
Description of mmcshext.dll from Microsoft
MMC is a Windows-based multiple document interface (MDI) application that heavily uses Internet technologies. Both Microsoft and ISVs extend the console by writing MMC snap-ins, which perform management tasks. The MMC programmatic interfaces permit the snap-ins to integrate with the console. These interfaces deal only with user interface extensions—how each snap-in actually performs tasks is entirely up to the snap-in. The relationship of the snap-in to the console consists of sharing a common hosting environment, and cross-application integration. The console itself offers no management behavior. Snap-ins always reside in a console; they do not run by themselves.
