In a moment of insanity I let myself be suckered in by an ad for Microsoft Bing, background images. That thing is horrible. Awful images, and it clutters up everything.

I went to "Installed Apps" and uninstalled it. That had no effect.
I then went to Control panel and Installed programs." It is listed there but has no uninstall option shown.

How do I undo my stupidity and get rid of this monster?
