Windows 10 19H1 18334 brings gaming improvements, with an option to play State of Decay for free for a limited time. Microsoft is looking forward to get feedback about any problems you may encounter during installing and launching the game. This option wont be available to everyone as there are only limited slots, so you might want to install this build ASAP (Microsoft does promise to open up more slots over the next few weeks).
