I think the Windows update corrupted the Bluetooth software. I turned the computer off, unplugged, pressed the start button for 10 seconds (this completely discharges the power), then restarted and looked for the device information and deleted the unknown one. Dell has a system to survey the computer to see what's missing and offered up the drivers for the WiFi/Bluetooth combo card. I then had to let Windows do it's big update again, but the Bluetooth stayed put this time. No dust disturbed.

I've taken the step to get my hair cut (finally!) and to set up a consultation as far as the cataracts. There are lots of ducks to line up for the surgery, the haircut, not so much. Short term and long term goals addressed in the same day.
