Windows 10: What is the floating window on my screen and how do I get rid of it?

This window floats in the top middle of my screen. It sits on top of my other apps, and I cannot click it. It has a small arrow pointing up to a window. Does anyone know what causes it and how to get rid of it?

Windows 10 strange unnamed floating text on the screen


As per the attached screen shot.
Not too sure what causes that text to float on the screen no matter what page or windows or application is running, it is floating on top.
is there a way to reset it other than Restart and or Logout / Login ?...

In the first post OceansBlue asked "what causes that text to float on the screen no matter what page or windows or application is running" by which I understood that when he / she boots up the computer the word Training immediately pops up and remains on the screen all the time.

In the second, however, OceansBlue suggests that it disappears after the restart, so I'm a bit confused now.

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
