If you mean "create an instance of it", any way you like: it
depends on how you package your COM object. If you package
it as a self-registering COM server in .ax file, register it
an use CoCreateInstance(), like most of the sample do.

IFilterGraph::AddFilter() or IGraphBuilder::AddFilter().

GuidGen.exe in the Platform SDK or VisualStudio and other
SDKs.
