or this:
To disable autoplay for cd/dvd drives and removable media
1: Copy & Paste the following into Notepad:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer] "NoDriveTypeAutoRun"=dword:000000b5
2: Save as a registry (.reg) file
3: Run the file to add the settings to the registry and there you have it - no more autorun or pop-ups!
