Windows 10 is being annyoing. Why?

[Windows Central Question]

SO after the November Update I keep getting this weird pop-up box that's completely black and only appears for a split second. But the reason its so annoying is because when it happens it make me go back to the start screen no matter where you are. This is really annoying when I am playing COD are something like that and it happens it makes me stop for a second and makes me click the icon again! I have a game that sometimes crashes when you minimize it. And its really annoying. Can someone help?
