Hmm, I haven't seen that before.

I found an article saying it is a new Windows 10 widget "rolling out" to users of recent versions. Probably somewhere in here there is an explanation of how to turn it off (I didn't read very far):

https://www.windowscentral.com/how-use-news-and-interests-taskbar-widget-windows-10

I figured it out on my own. Right click on the taskbar and you will see "news and Interests" Click the arrow and select "turn off"

Easy peasy. I just didn't know what it was called to Google it.
