Warning: Adding or Excluding certain items my put you at risk.
This warning will be on all the Power User Features. Since everything you exclude or let through is a risk. Please be sure you know what items you are excluding or allowing through. If you are unsure, it won't hurt to ask me. I'm here to keep you safe.
Device Control is where you can lock out hardware from gaining access to your system. By default nothing is locked down, I don't know your hardware and wouldn't know what's safe to lock out. But you should find it pretty easy to lock out various devices. Just access the Power User menu and go to Device Control.
As you can see you have a wide variety of devices to pick from. Managing which devices have what control is easy. Just click on the device you want to control and select what kind of access it has.
