AutoRun runs a program when a CD is inserted into a Windows computer - see below for advice on Apple Macs.
If Windows finds a (plain text) file called AUTORUN.INF in the root directory of a CD then it follows the instructions in this file to run a program. This example AUTORUN.INF file tells Windows to run program setup.exe (from the root directory of the CD):
[autorun]
open=setup.exe
icon=snazzie.ico
