Windows 8 is the latest release of the Microsoft’s flagship Windows operating system and is designed to run on desktops, laptops and tablets. Three free Preview Editions were made available for download before the OS was finally released in August 2012.
There are four editions of Windows 8: Windows 8, Windows 8 Professional, Windows 8 Enterprise and Windows RT. The first three have similar hardware requirements to the comparable versions of Windows 7. Windows RT is designed to run on tablet computers with the ARM architecture. There are no retail versions of Windows 8 Enterprise and Windows RT, so they can only be obtained by buying hardware which has them bundled.Windows 8 has a new GUI based on Microsoft’s Metro design language. It features a tile-based Start screen similar to the one used in the Windows Phone operating system. Each tile represents an application and can display relevant, for example
the tile for an e-mail application might display the number of unread messages. These “Windows 8-style” applications can only be obtained from Microsoft’s Windows Store.The conventional GUI for running desktop applications can be accessed from a tile on the new Start screen. The Start button found on the taskbar in older versions of Windows has been replaced by a Start button on the new charm bar and a hotspot in the bottom-left corner.For further information, see the Wikipedia article on Windows 8.
