How to identify system shut down or reboot events in exit handler?

Question

I have the following code to identify whether a process has exited or not. When it exits I am creating a notification in my application.

Process[] processes = RunningInstancesByName("MyService");

while (processes.Length <= 0)
{
  //Thread.Sleep(100);
  processes = RunningInstancesByName(name);
  }
  Process process = processes[0];

  process.EnableRaisingEvents = true;
  process.Exited += this.Installer_Process_Exited;
  AddExitEvents(name, eventHandler);

  return process;
}

How do I identify whether this exit was triggered by a Windows shutdown or restart? Because if it is so, I should not create a notification through my application? Is there a way to identify whether this process exited because of such shut down or restart events? Please advice.
