After todays update I can't play games in windowed mode

[Nekoszowy]

I hate fullscreen mode and before update I could switch to window mode, now there's no arrows next to minimalize and close in up right corner of screen. I'm on laptop, and I didn't found any other posts like this(probably most of people like fullscreen),
Every app from shop, like Pasjans, Dragon Mania Legends, Dungeon Hunter 5 etc are "not allowed" to play in windowed mode. Help.:crying:
