The genuine es.dll file is a software component of COM Services by Microsoft.
Es.dll is a DLL (dynamic link library) associated with the Supports System Event Notification Service (SENS) program. DLL files store data, code and resources needed by one or more programs in order to function correctly. If this service is stopped, any services dependent on it will fail to start. SENS provides automatic distribution of events to subscribing Component Object Model (COM) components. These components are used for communication between system processes and object creation. The Component Object Model is a standard for binary interfaces introduced in 1993 by Microsoft. Microsoft was founded in 1975 by Bill Gates and Paul Allen and quickly rose to prominence following the launch of their popular operating system, MS-DOS, for early personally computers. Microsoft began developing graphical user interface and the distinguishable Start-button on the introduction on Windows 95. Further additions like networking and security soon followed.
