Powershell profile "on exit" event?

I'm looking for a way to automatically do some clean up tasks when the PowerShell session quits. So for example in my profile file I start a process which needs to run in the background for quite a lot of tasks and I would like to automatically close that process when I close the console.

Is there some function the PowerShell automatically calls when closing the session as it does with `prompt` when displaying the prompt?

There is the [`Register-EngineEvent`][1] cmdlet which you can use to attach an event handler to the `Exiting` event:

Register-EngineEvent PowerShell.Exiting -Action { ... }

Note however, that this event will not be fired if you close the console window.

For an example of how to on exit event. In this case, saving the History of commands on to a file, and maybe stored in a $Profile.
