First source

If you look in the registry under HKEY_CLASSES_ROOT\.bmp.

The (Default) value will show you the default associated program. In my case, this shows Paint.Picture, which links you to HKEY_CLASSES_ROOT\Paint.Picture.

Under HKEY_CLASSES_ROOT\.bmp you'll also find the subkey OpenWithList which contains subkeys to "Open With" applications.

Second source

Under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts you'll also find a list of fileextensions. Look for .bmp, a subkey OpenWithList exists there too. I think this source is what you need.
