I developed a dll using ATL wizard and choose the option
of merge proxy stub.
And I observed after registering the dll the
proxystubclsid32 key under HKCR/Interface/IID still points
to the CLSID{0000002F-0000-0000-C000-000000000046} of
default marshaller.

Is it a bug associated with Regsvr32 ? Any Knowledge base
article is available for this.
or the changes to proxystubclsid32 key is not reqd?

Thanks.
Jack
