Is there a suggestion as to what icons should appear in notification area? There are lots in there I do not know where came from. Suddenly appeared. Maybe I set it to show them; not sure. But I wondered if they all need to be there and which need to be shown or hidden, or is it simply the choice of the user. I set it to hide the ones I do not recall as showing up regularly, like ever time PC is on. And there is an arrow next to the icons that let me Show Hidden Icons, and I also know where to choose to show or hide if I wish.
