    The first version of Windows

    Redmond, Washington, U.S.
    1985

    The first versions of Windows (1.0 through to 3.11) were graphical shells that ran from MS-DOS. Later on, Windows 95, though still being based on MS-DOS, was its own operating system, using a 16-bit DOS-based kernel and 32-bit userspace. Windows 95 introduced many features that have been part of the product ever since, including the Start menu, the taskbar, and Windows Explorer (renamed File Explorer in Windows 8).

    Microsoft introduced Windows as a graphical user interface for MS-DOS, which had been introduced a couple of years earlier.

The introduction of Windows XP aimed to unify the consumer-oriented Windows 9x series with the architecture introduced by Windows NT, a change that Microsoft promised would provide better performance over its DOS-based predecessors. Windows XP would also introduce a redesigned user interface (including an updated Start menu and a "task-oriented" Windows Explorer), streamlined multimedia and networking features, Internet Explorer 6, integration with Microsoft's .NET Passport services, modes to help provide compatibility with software designed for previous versions of Windows, and Remote Assistance functionality.

    Friday Oct 26, 2012

    Windows 8, the successor to Windows 7, was released generally on October 26, 2012. A number of significant changes were made on Windows 8, including the introduction of a user interface based around Microsoft's Metro design language with optimizations for touch-based devices such as tablets and all-in-one PCs. These changes include the Start screen, which uses large tiles that are more convenient for touch interactions and allow for the display of continually updated information, and a new class of apps that are designed primarily for use on touch-based devices. The new Windows version required a minimum resolution of 1024×768 pixels,[36] effectively making it unfit for netbooks with 800x600-pixel screens.
