MS Windows 8.1 Pro
With Windows 8.1 Pro, you can start from the desktop you've always known or the modern Start screen with apps as Live Tiles. You can use touch, your mouse or the keyboard – whatever's easier. And you can use the accessories you want because Windows is compatible with nearly all of them. Plus, you can search your PC, the web, the cloud and apps at the same time with Bing Smart Search. Just access the Search charm from the right side of your screen.
