Welcome to the Release Preview Windows Store. In this post, we’ll describe a few of the improvements we’ve made to the user experience. We’ll also touch on a few updates that we've made to our app certification policy, in an effort to ensure guidelines and expectations remain clear. And, of course, we want to encourage you to dive in and explore the hundreds of preview apps currently in the catalog—including the first desktop app listings. These apps are just the beginning—we’ll continue to add apps during the Release Preview timeframe.
