Seems a (somewhat misformed) message of a program running.
- Does it happen also if you boot into Safe Mode (Google how to do that in Windows 10, if you don't know)?
- Any suspect entry in the list of items that run at startup (a tab page in Task Manager)? That disable that, reboot and see if it disappears.
- Finally, delete all running processes (Explorer excluded, services not necessary since those don't display anything on the screen) in Task Manager. The last one for this text disappears is the culprit.
Basically, this center dialog text won't ever disappear from the center of the background display no matter what I do. Change personalization issues, etc.
