ShellRun is a program to display a web page when your CD or DVD is inserted into a Windows computer. ShellRun can alternatively display a PDF file, Word document, MP3 file or any other document. AutoRun works in Windows only. ShellRun displays a small pop up window and then attempts to run the appropriate viewer program to show your file. Put ShellRun on your CD along with a suitable AUTORUN.INF file. A retail version is available.
