Recently I did a uninstall of Nero 7 from my Windows 7 computer and installed Nero 9. After I had completed this I found that there were many orphaned Nero 7 AutoPlay handlers left in the options list. I had to manually remove the options from the list using the Windows Registry Editor (regedit.exe).
To do this, execute regedit.exe, then navigate to the following location in the registry editor.
HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ AutoplayHandlers
At this location of the registry you are concerned with two different folders, the Handlers and EventHandlers folders. The Handler folders holds the reference to the software that is executed. The EventHandlers folder contains the different AutoPlay option lists.
First you will need to go through the Handlers folder and delete all folders associated with the software that is showing up. After you have done that then go through the EventHandlers folders and remove all of the references to the Handlers in each event. I had to go through each individual EventHandlers subfolder.
