We've got the system tray disabled for all our students in this school, mainly to stop them accessing graphics control panels and the like that enjoy running in the system tray. However this poses a problem, which is the students don't get any form of battery monitor whe or a low battery warning etc. when they're using laptops.
I don't want to enable the system tray if I can help it, so I'm looking for a simple battery monitor application which will sit at the top/bottom of the screen and inform the user of the battery state and when it's running low. Anyone know of a utility that will do this? All the ones I've found run in the system tray, which I explicitly want to avoid.
Failing that, anyone know how I can control what's visible in the system tray via Group policy or simelar so I make sure only the volume control and battery status is visible.
