Windows 8 ISO Download - Available Editions

Windows 8 ISO is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems. Development of Windows 8 started before the release of its predecessor, Windows 7, in 2009. It was announced at CES 2011, and followed by the release of three pre-release versions from September 2011 to May 2012. The operating system was released to manufacturing on August 1, 2012, and was released for general availability on October 26, 2012.

Windows 8 was released to a mixed critical reception. Although reaction towards its performance improvements, security enhancements, and improved support for touchscreen devices was positive, the new user interface of the operating system was widely criticized for being potentially confusing and difficult to learn, especially when used with a keyboard and mouse instead of a touchscreen. Despite these shortcomings, 60 million Windows 8 licenses have been sold through January 2013, a number that included both upgrades and sales to OEMs for new PCs.

On October 17, 2013, Microsoft released Windows 8.1. It addresses some aspects of Windows 8 that were criticized by reviewers and early adopters and incorporates additional improvements to various aspects of the operating system. Windows 8 was ultimately succeeded by Windows 10 in July 2015. Support for Windows 8 RTM ended on January 12, 2016; per Microsoft lifecycle policies regarding service packs, Windows 8.1 must be installed to maintain support and receive further updates.
