title: 'End Task' in Task Manager always sets CloseReason.UserClosing
body: <p>I want to log if a customer tries to force close the application. I'm aware of having no chance to catch a process kill. But it should be possible through the main form closing event to get informed about the 'CloseReason.TaskManagerClosing' reason.</p>
  
  <p>But any tests I did under Windows 8.1 I always got a CloseReason.UserClosing reason. But in this case (compared to a normals CloseReason.UserClosing) I've about 0.2s to run user code afterwards my program is killed!</p>
  
  <p>Is this a new behavior in Windows 8.1?</p>
