title: In Windows, does "The exception unknown software exception (0x40000015) occurred in the application" mean STATUS_FATAL_APP_EXIT?
body: <p>At shutdown (initiated by an UPS) my application crashes and a messagebox appears. </p>
  
  <p>The text in the messagebox is "The exception unknown software exception (0x40000015) occurred in the application".</p>
  
  <p>I browsed <code>ntstatus.h</code> and found <code>STATUS_FATAL_APP_EXIT</code>? If it were right, why the message box say "unknown software exception"?</p>
