Windows - Unknown file type and Windows Web Search

Question

In MS Windows, when you double-click a file with an unknown file extension, the OS presents you with a message giving you a choice:

1 - use the web service to find the appropriate program

2 - select a program from the list

Is there a way to "register" the extension of your file with MS (or by anyone else) so that your application displays as a result when you select "Use a web service to find the appropriate program"?
