Windows 8.1 on a 4k Monitor

Ok, just purchased a 39" 4k monitor for development. Works great running Win8 in desktop! However I just can't stand it with Windows Store Apps. The fact that I have a 39" 4k monitor and Windows Store apps run full screen is very irritating.

I think Microsoft should allow Windows Store Apps to run inside a window in the desktop. The would go a long way of solving the issue everyone is having with Win8. If you have a tablet 10" or less then sure run the apps full screen. But come on running everything full screen is just ridiculous... Fix it...!

Vertical snap panes is not a replacement for Windows. We want Microsoft Window(s) back... not Microsoft Window.

PS- I love everything else about Win8
