Windows 8 (Windows 8.x) is the most recent stable release of the Microsoft Windows computer operating system. The final version for everyone was released everywhere on October 26, 2012. The president of the Windows Division Steven Sinofsky said: "With this system we shall make the biggest change from Windows 95", as they have removed the Start button/menu (they were first put in Windows 95).
On February 29 2012, Microsoft released a Beta version of Windows 8.0 known as the Consumer Preview. After the Consumer Preview, a final preview named "Release Preview" was released on May 31st, 2012, and the final release was on October 26 2012. Windows 8.0 is codenamed "Windows Server 8.0".
The latest version released is Windows 8.1 Pro (Windows 8.1 Professional) which has enhanced features. In September 2011, Microsoft released the Developer Preview version. It was released for developers. Windows 10 is currently being developed to replace Windows 8 and 8.1.
Features[change | change source]
Windows 8 provides a new graphic user interface – Modern (also called Metro) UI (suitable for phone, tablet, notebook and classic PCs). This interface shows “tiles” which work as links and also as interactive widgets (RSS, weather, e-mails). Modern UI is optimized for touchscreen, but can be controlled by mouse and keyboard. Windows 8 still offers the classic desktop interface as an option.
Although Windows 8 is lighter than Windows 7, it demands more pixels on the screen. The minimum is 1366 x 768 pixels, which affects many users of laptops that have a maximum resolution of 1024 x 600 pixels. Some users with old hardware have for that reason continued to use windows 7. Windows 8 will work on resolutions lower than this, but some features will be unavailable.
File Explorer, formerly called Windows Explorer, has a new ribbon bar interface. It can pause and resume a file transfer, and has an improved method to resolve conflicts when two files have the same name.
