Registering/unregistering a DLL or OCX has nothing to do with the add-ons
list in IE. It simply makes adjustments to the registry as required for
Windows to know where the DLL/OCX is located and it's GUID and classname, so
that should an application request a resource from that DLL/OCX it can do
so. The add-ons list in IE is controlled by a different registry key - to
remove items from it you can delete the appropriate entry, or simply use the
uninstall feature of the component. To add add-ons you should run the
install routine for that add-on rather than attempting to manually create
the registry value.
