 * lpAppFileName  [I] The filename of the application executable

 * RETURNS
 * TRUE on success, FALSE of failure
 *
 * NOTES
 * Wine doesn't use this data but stores it in the registry (in the same place
 * as Windows would) in case it will be useful in a future version
 *
 * According to MSDN this function should succeed even if the user has no write
 * access to HKLM. This probably means that there is no error checking.
