The new Start screen has all of the information you care about in one place, such as contacts, the weather, and the next appointment on your calendar. Windows 8.1 is truly yours: websites, playlists, photo albums, contacts, and your favorite apps are front and center.
The tiles on your Start screen are brimming with content, and they change and update in real time so you can see what's going on and stay on top of things. You can share and connect with other people in a couple of clicks, and get real-time updates about things like news, sports, and what your friends are up to. Check your schedule or get the latest weather forecast. Tiles are a quick way to see it all. Launch apps, switch between tasks, and check notifications without digging for information.
Windows 8.1 also incorporates the PC desktop that you're already familiar with. In the desktop, you'll see that the settings and features you used in Windows 7 are still there
