How to Configure the AutoPlay Settings in Windows 7?

Hi to everyone,
What is all about Windows 7 autoplay fix utility? Can you give me some cure or solution about this autoplay application? I usually get this autoplay warning every time I insert some usb pen device in the computer or if I am going to watch movie using the laptop, but now it seems like I cannot see the autoplay warning. How can I restore it?
Your suggestion is very much welcome.
