Setting description for service inside registry

Hello everybody,


I installed PDFCreator as a service on Windows server. Now I want to set the description of this service such that it appears in the Services utility instead of a blank line. I searched the registry under HKLM\\Software\\PDFCreator for anything like "Description", "ServiceDescription" or so but did not find anything. Can someone please tell me which key I have to insert to give PDFCreator such kind of textual description? Thanks.
