For Digital Cameras, it's probably stored here:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\StillImage\Registered
Applications

For other removable devices, here:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Explorer\AutoplayHandlers

I just thought of a follow-up question:

Where does Windows pull the list of programs from, that the camera can open?
How does the camera know that these programs will work? (They all
do--ACDSee,
Photoshop Elements, Windows Scanner and Camera wizard, etc.) I imagine it
must be somewhere in the Registry, but where?

It's one thing for File Associations to know that inserting a DVD Video
starts up PowerDVD, or something, but how does a *device* know this? Very
curious about this...
