ShellRun

ShellRun is a program that will 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. For example, for a web page, ShellRun asks Windows to start the default browser to display the web page.
Put the ShellRun.exe runtime on your CD along with a suitable AUTORUN.INF file. Remember to print manual instructions on your CD for users who have AutoRun disabled, or for those who have other sorts of computer.
ShellRun can also be run from a command line prompt or using Start+Run to display a file or URL.
The development kit has an install/uninstall facility. The development kit also contains an article describing how to put a web site on CD, i.e. produce HTML CDs.
The retail version lets you customize or remove the ShellRun pop up window, provide a menu of commands, and determines what to do if a suitable viewer program is not available.
