I run a 4k monitor and then two side 1440p monitors. So i have my games set to borderless windowed mode so i can easily switch to the other monitors in the middle of gaming. Before i did this clean install of anniversary update if i had a game open and hit alt tab the taskbar of the main monitor would appear over top the game and i could use it. Now that i did the update though when i press alt tab it doesn't have this effect unless it happens to be a program on the same monitor as the game which rarely is the case. Any idea what setting could be causing this?
