Windows XP does not autoplay CD's

This one can be annoying since the CD does not autoplay and you have to go to my computer and click on the CD ROM icon to play the CD.
the best solution that worked for me from Microsoft was the one about editing the registry, locating the following key :HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\CDRom and changing the value of Autorun to 1.
After changing it I reboot the computer pop in any CD and it now autoplays.
Great.
