I would like a third party software program to be added to the Autoplay options.

There was a registry hack that allowed this in XP but as yet I haven't been able to locate one for vista.

No hack needed: http://www.windows-vista-update.com/..._Autoplay.html

thanks for the reply.

But the problem is that I can not choose from other programs. All that is listed in these dropdowns are the default programs.
Iwant to ADD other programs to these dropdowns.

I'm not 100% sure, but, if you set it to "Ask me every time", it may let you select another program.
