When Win10 was initially released (IIRC 1507, 1509), it won't support title bar coloring. That's horrible to detect which window is foreground. At future version, they added an option to coloring title bar. I suspect that what is foreground windows is not important for touch oriented device, but it's problem for keyboard operation.
