This only started happening recently, presumably after updating my bluetooth driver from windows update. I've tried going into the system tray options and making the icon "hide icon and notifications", but it just forcibly comes back when I restart the computer again. I do not want my bluetooth radio to be discoverable.
I've also gone into my bluetooth settings and unchecked the box to notify when devices want to connect, but that didn't help either. I do use bluetooth so I do not want to disable it.
