Remember the Vista Battery Saver? It's a freeware utility that performs clever power-management tricks, like turning off Aero Glass when your notebook is running on battery power.

Just one problem: Vista Battery Saver requires the Microsoft .NET Framework, and as such it might be trickier to deploy on your users' systems.

Enter AeroFoil, a tiny (384K!) System Tray utility that performs the same key task as VBS: It turns off power-sapping Aero features when you unplug your notebook from the wall.

And when you plug it back in again, AeroFoil restores Aero to its former luster. Because there's no .NET Framework required, you should be able to deploy this anywhere and everywhere without any added configuration hassles. This is definitely a worthwhile little app for road warriors, who always need more juice than their battery can provide.
