Many times, you don’t want your CD or DVD to process the Autorun file. You know what you want to do, and you do it. But, disabling the Autorun feature isn’t the easiest to find. In fact, you have to edit the registry to do it. Here is how.
1. First, open the Registry Editor (Start, Run, type regedit -or- Start, type regedit in the search box and press enter).
2. Navigate to the key Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\cdrom
3. Right click the key on the right pane titled AutoRun and click Modify. Change the 1 to a 0.
4. Restart your PC, and the Autorun feature is disabled for your CD/DVD drive. This can be very handy for those that dislike the Autorun feature.
