How to Disable CD Autoplay in Windows

To disable autoplay in Windows XP Professional, do the following: 

Start > Run > gpedit.msc 
(Left Pane) Computerer Configuration > Administrative Templates > System 
(Right Pane) Set "Turn off autoplay" to "Enabled" 

(In the snap-in, it says, "Note: This setting does not prevent autoplay for music CDs." This means that the audio tracks on the CD will still play automatically--however, it *will* disable autoplay on the "data track" of the CD, which is what runs arbitrary code, like installers for evil DRM software, automatically.) 

To disable autorun in Windows XP Home Edition, do the following: 

1.  Click Start> Run> regedit
     Find HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\Services\Cdrom

     Double click “Autorun” the value is set to "1" by default, change it to zero. Click OK 

     Now restart, that’s it!

2. Start > Run > regedit 
    Find HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Policies\Explorer 

    Make a new value called NoDriveTypeAutoRun of type DWORD. Make its value "0x000000b1" (hex). 
    Reboot to be sure it takes effect. 

    To re-enable autorun in Windows XP Home Edition, go back and set the value to "0x00000091" (hex).
