Windows 8.1 system requirements

Windows 8.1 is the next step forward to Windows 8. It supports the widest possible range of devices, from the smallest tablets and convertibles to the sleekest and highest-powered notebooks, all delivering the latest advances in screens, battery life, performance, and design.

The Windows 8.1 update changes key aspects of the Windows 8 operating system. The update contains a number of improvements throughout the operating system, but primarily focuses on improving functionality within the new Windows UI shell and Windows Store apps, expanding search capabilities, adding support for more emerging technologies, and features intended to improve the usability of the desktop interface following the changes that were made to it on Windows 8 (such as restoring a visible Start button, the ability to disable hot corners, and the ability to skip the Start screen when logging in).
