A question about IShellLink interface and the COM object.

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

We can query the object implementing IShellLink for IPersistFile to
create a shortcut file.

But if I don't know this tip, how can I know that the object which has
implemented IShellLink also has implemented IPersistFile???

Maybe this is a topic about using Microsoft COM objects, however, I
cannot find any guidelines through msdn.

thanks.
