Windows 8 was released on October 26, 2012 and is the sequel to Windows 7, released in 2009. The system was followed by Windows 10, released July 29, 2015.
Windows 8 introduced a new user interface based on Microsoft’s “Metro” design, which has a startup image that consists of tiles, the content of which is automatically updated and represents programs.
The new user interface was first used on Zune devices, Microsoft’s mp3 players, and later on Windows Phone 7. It is designed to be used with a touch screen.
New to Windows 8 was also Windows Store, intended for purchase of applications as it is known from e.g. Mac App Store and Google Play. It is also possible to synchronise programs and settings across various devices running Windows 8, e.g. between Windows Phone 8 and Microsoft Surface or a desktop PC.
