title: Disable "chrome is out of date" notification
body: <p>I have a touchscreen application optimised and running in a Chrome kiosk mode. It runs totally offline and due to some updates to Chrome breaking the application I've had to lock it to a fixed version of Chrome (v37.x). 
  I've been able to prevent Chrome from auto-updating itself using the ADM/gpedit methods (<a href="http://www.wikihow.com/Completely-Disable-Google-Chrome-Update" rel="noreferrer">http://www.wikihow.com/Completely-Disable-Google-Chrome-Update</a>), but Chrome is now displaying a message on screen to say it is out of date.</p>

  <p>Has anybody been able to find a way to disable this notification?</p>
