Here is a solution for the Geeks; it modifies the Windows registry:
1. Start RegEdit (regedt32.exe).
2. Go to HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Cdrom.
3. Edit the Autorun value to '1' to enable autorn, and '0'
to disable autorun.
4. Close RegEdit.
NOTE: You may have to restart the system.
A simpler solution (not guaranteed to work if autorun has been disabled in the registry, as in my case) is:
1. Right-click on the drive.
2. Choose properties.
3. Choose Autoplay.
4. Choose the action you want to take for various file types.
