The Windows Store will go live on late February 2012 together with the release of Windows 8 beta, but paid applications will appear only after the launch of Windows 8.
Of course, the new Windows Store isn't just for consumers, enterprise apps will also be available to fulfill your every business need. IT admins can deploy apps in a local version of the store, so that everything stays nice and secure on the internal networks. Not only that, but some secret sauce ensures that both enterprise and personal apps can be managed seamlessly on that slick new Windows 8 slate of yours. As for developers, Microsoft takes the now standard 30 percent cut of every app you sell in its store, but once you've sold $25,000 worth of software, that drops to 20 percent.
