Microsoft Windows is a series of software operating systems and graphical user interfaces produced by the US company Microsoft.
The first version of the system was called Windows 1.0 and was launched on November 20, 1985 as a graphical interface for the MS-DOS operating system, which Microsoft bought in 1980 and has further developed since.
The subsequent editions of the Windows environment – Windows 2.0, Windows 3.0, Windows 3.1, Windows 95, Windows 98 and Windows Me were all based on the underlying MS-DOS operating system.
In parallel with the early development of Windows, a group of Microsoft programmers, led by David Cutler, worked to create the operating system that later became known as Windows NT. From the beginning, the goal of Windows NT was to create a new and more abstract, platform-based and multi-user-oriented operating system that was more stable and able to compete in the markets dominated by Unix at that time.
Over the years, Microsoft released new versions of the MS-DOS-based Windows alongside (for consumers) and the NT-based Windows NT (targeting companies), but during the development of Windows XP, they decided to merge the two operating systems into one product. Since then, all versions of Microsoft Windows have been based on further developments of Windows NT.
Windows operating systems are most common in personal computers and servers, but special versions are also available for devices such as smartphones and PDAs, as well as a version designed specifically for so-called embedded devices, such as audio and navigation systems for cars.
Windows 7 Microsoft Windows 7 is an operating system for both desktops and laptops, released by Microsoft on October 22, 2009. The system contained NT-version 6.1. and was initially called Blackcomb and later Vienna during the development. The first Service Pack was released February 22, 2011.
Windows 8 Microsoft Windows 8 is an operating system that has a classic metro design known from Windows Phone, but the system is designed for both touch and mouse operations.
The latest version of the Windows client version is Windows 8.1; The latest version of the server version is Windows Server 2012; The latest version of the mobile operating system is called Windows Phone 8.
Windows 10 Windows 10 was launched by Microsoft on July 29, 2015. Windows 10 is the sequel to Windows 8.1, which was launched in 2013. Windows 10 restores focus on the desktop environment. Among other things, the well-known start button is revoked, which was otherwise removed in Windows 8, and the amulet menu, introduced in Windows 8, was removed. With Windows 10, Internet Explorer is replaced by Microsoft Edge as the default browser.
