The warning came from Phil McMichael, business director of Bang & Olufsen in Windsor High Street and newly elected chairman of Windsor District Chamber of Commerce.
Mr McMichael said there was concern over the preliminary 'preferred options' document, which is on view as a new Royal Borough plan that will outline future policies for the area is prepared.
He said: "What became extremely apparent to the chamber and of great concern was that Maidenhead was being seen as the economic driver for the borough, while Windsor was seen as the pretty little tourist venue."
Mr McMichael was speaking at a meeting in the Guildhall yesterday of the forum preparing a Neighbourhood Plan for Central Windsor.
He said: "We have the opportunity within the Neighbourhood Plan to bang some heads together in the borough till they realise Windsor forms a major part of the borough's economy."
