The release of Windows 8.1 that precedes the Windows 8 comes with some added features. It received lots of important updates since it's first introduced, including the major update 1 for missing features in the predecessor. They are the power button and Search bar at the Metro screen and chance to boot directly to the desktop environment as a choice(this option can be controlled at the Taskbar and Navigation Properties). There is also the most noticeable feature of being able to pin Start-up Metro applications onto your desktop Taskbar. Above all there is the return of the Start button. The Start button this time is different from its former function. It is now a place for applications, programs, links and other Windows utilities.

When you have successfully installed Windows 8.1 on your system with all interest and the metro features are in order without having critical error there is need to feel nothing is left to be addressed. While connecting to the internet becomes a problem, the WiFi tab is in grey meaning it is the culprit. It is to the left-hand corner of the screen at the Charm bar, which means the WiFi adapter is disabled requiring manual effort.
