All the Windows Store export options are under the "Windows Store" export option. There's a new item in the list in the next dialog in r209 for Windows 10 export.
Thanks, but now I see a new problem, so how do I compile this to a .exe? I just get a bunch of .js files that only get launched from windows visual studio. Also the performance is worse than nw.js. But I thought the benefit of using windows studio is it could always compile? it doesnt let me. Any guides for compiling?
