Opens 'Set Default Programs' window, despite being passed the name of a non-registered application
This method currently has undocumented behavior in Windows Vista where it will open the the Set Default Programs window when passed the name of a non-registered application, despite returning E_INVALIDARG. Do not rely on this behavior as it fixed in Windows 7 and above.
