Check out ModernMix, a new application from StarDock, which aims to bring back the familiar resize/close buttons to your Metro apps, as well as the ability to run Metro apps in a Window on your desktop, rather than taking up the entire screen.
"ModernMix is a revolutionary new program that lets you run Windows 8 "Modern" apps in a window on the desktop. Windows 8 Modern apps, also known as Metro or RT apps, will use the full screen on your display regardless of how much of the screen they really need. As a result, that weather app, mail program or stock ticker is going to use the entirety of your computer display," StaDock explained on their website. Currently in Beta and available for $4.99, ModernMix is pretty straightforward and simply runs Windows 8 Metro apps in a window, with the ability to display and pin apps on your taskbar. You can even close each individual app by pressing the familiar red close button on the top right of the window.
This software brings back the familiar nature of having software open up as windows on your desktop with the ability to close/resize. While this is not Microsoft's vision of how Windows 8 should be, those who missed these features from Windows 7 will finally be happy (after paying $4.99 of course). Hit the download link to grab the Beta! This software does not work on Windows RT.
