Turning off the autoplay

By default Windows Xp will automatically detect the presence of any disk inserted into an optical drive on your system. As soon as such disks are detected, any applications, audio or video files on these disks will automatically be launched. This autoplay functionality can be annoying to some, and can also lead to unwanted and potentially insecure software being automatically installed. To disable autoplay functionality, make the following change:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDRom]

Autorun=0

Setting this DWORD to 0 disables autoplay, setting it to 1 enables Autoplay. Note that instead of using this tweak, you can temporarily disable Autoplay behavior at any time simply by holding down the SHIFT key while inserting a disk.
