I've been using Win10 for a while now, and I still can't figure out what one of these tray icons is supposed to mean -- symbolically that is. So, the volume and message icons make perfect sense, but what the heck is the network icon supposed to represent? Is it a PCI card? or maybe a monitor with a lump on the left side. And is that a tiny "T" inside the lump? And what is that lump. You'd think after designing icons for decades they could make this a bit more... user friendly or something. Any ideas of what this icon is?
