Re: Detecting installed applications for specific file type

You're right Joe. It's stored in the registry under with the document type
and icon to be displayed in Explorer. If there were more than one it would
cause a conundrum for Explorer (trying to decide which to use). However,
there is also a list of "Open With..." in case a type is opened with more
than one application. It is retained as a history.

You can look under HKEY_CLASSES_ROOT for the extension type (I.E., .doc) to
get the document name then look under the document name to get the
information about which program starts it.
