The COM Library is a system element that gives the mechanics of COM. The COM Library provides the flexibility to make IUnknown calls throughout processes; it additionally encapsulates all of the “legwork” related to launching parts and establishing connections between elements. Sometimes, when an software creates a COM element, it passes the CLSID of that COM part class to the COM Library. The COM Library makes use of that CLSID to look up the related server code within the registration database. If the server is an executable, COM launches the EXE and waits for it to register its class factory through a call to CoRegisterClassFactory. (A category manufacturing unit is the mechanism in COM used to instantiate new COM components.) If that code occurs to be a DLL, COM masses the DLL and calls DllGetClassFactory.
