How to avoid auto play of CD ?

Hey this time no registry trick even though there are ways in registry to do it. In earlier operating systems only those CD that had autorun.inf file in their root directory were able to execute on its own but with advent of WINDOWS XP it has become possible with just about anything. Well sometimes it is good but there are other times when you want to avoid this part of automation. What would I do. Simply press SHIFT key when you enter a CD in your CD drive. It won't Auto play. For those of you, who do want a registry hack. Here it is:
Open Registry and navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer] and look for key "NoDriveTypeAutoRun" and set its value to 185 (decimal). This would stop autoplay.
