Start your CD or DVD professionally. ShellRun neatly AutoRuns your chosen file as soon as your CD is inserted into a Windows computer. ShellRun displays a small pop-up window and then attempts to open a filename, i.e. run the viewer program that is associated with the filename extension. ShellRun is typically used to show a Web page in the user's browser but may also be used any other file type. A retail version of ShellRun lets you customise or remove the pop-up window, and cope if a user has not got a suitable viewer installed.
