MICROSOFT WINDOWS

Microsoft Windows, or simply Windows, is a metafamily of graphic operating systems developed, marketed and sold by Microsoft. It consists of several families of operating systems, each of which serves a specific sector of the computer industry with the operating system typically associated with the architecture compatible with IBM PC. Active Windows families include Windows NT and Windows Embedded; these can encompass subfamilies, for example Windows Embedded Compact (Windows CE) or Windows Server. Windows defunct families include Windows 9x, Windows Mobile and Windows Phone.



Microsoft introduced an operating environment called Windows on November 20, 1985, as an operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). [3] Microsoft Windows came to dominate the global personal computer (PC) market with more than 90% market share, surpassing Mac OS, which had been introduced in 1984. Apple came to see Windows as an unfair invasion in its innovation in the development of GUI as implemented in products such as Lisa and Macintosh (it was finally established in court in favor of Microsoft in 1993). On PCs, Windows remains the most popular operating system. However, in 2014, Microsoft admitted the loss of most of the general operating system market to Android, [4] due to the massive growth in Android smartphone sales. In 2014, the number of Windows devices sold was less than 25% of the Android devices sold. This comparison, however, may not be fully relevant, since the two operating systems traditionally target different platforms. Even so, the numbers for the use of the Windows server (which are comparable to the competitors) show a third market share, similar to the use of the end user.



As of September 2016, the latest version of Windows for PCs, tablets, smartphones and integrated devices is Windows 10. The latest versions for server computers are Windows Server 2016. A specialized version of Windows runs on the Xbox One video game console.
