With Windows 8, Microsoft introduces a brand new interface that feels designed more for tablets than for laptops and desktops. We'll help you find your way around the new OS and make the most of its features.
This charm is context-sensitive, so what appears when you click it depends on what you're doing at the time and what kind of devices you've connected to your Windows 8 computer or tablet.
Generally, you use the Devices charm to print from a Windows 8 app and to manage your printers and other connected devices. For instance, if you've got two or more displays connected to your device, Devices lets you control how the screens work.
