Windows 10 has some great features. Virtual desktops, integrated VPN, wireless displays, a browser that works, etc.
But you may not have noticed the included panoramic desktop wallpaper images. Users with multi-screen displays will discover that an extended desktop no longer means a repeated background image. Extending your desktop to another monitor will show a full panorama image.
And if you get bored with the handful included you can snag more for free from Microsoft. My current favorite is Bryce Canyon.
