Disable Autoplay through a registry hack

Autoplay is one of the most wildly annoying features I know. I just dislike inserting, let’s say, a TechNet CD, and have Windows open Internet Explorer and display a lot of useless information that I don’t care about.I would much rather browse through the file system of the disc, and go directly to what I need. Luckily, you can create a registry key to disable Autoplay:
 

1. Open the Registry Editor
2. Navigate through the Registry Editor to HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
3. Create a DWORD named NoDriveTypeAutoRun
4. Set the value to 000000FF
