Here’s how one user described the problem on Microsoft Answers forum:

Hi all,
I purchased a new computer earlier this month, and have been noticing a strange pop-up window that will either alt-tab any game that I have open in fullscreen or will overlay anything else i have open for half a second and then automatically close before I can do anything or even tell what it is. It happens every half hour to a few hours, seemingly at random.
