If you have the driver installed, you can find the EXE file to start the webcam by going to Start and typing 'webcam' in the search bar. Among the resulted programs, you should be able to find the icon for the webcam service. If you can't find the icon, go to the support website, search for your laptop and download the latest version of the webcam driver and the Dell Webcam Central. This is an utility that facilitates the use of your webcam.
