CoFreeUnusedLibraries function (combaseapi.h)
Unloads any DLLs that are no longer in use, probably because the DLL no longer has any instantiated COM objects outstanding.
Applications can call CoFreeUnusedLibraries periodically to free resources. It is most efficient to call it either at the top of a message loop or in some idle-time task. CoFreeUnusedLibraries internally calls DllCanUnloadNow for DLLs that implement and export that function.
