Windows Setup

Windows Setup is an installer that prepares a hard disk drive for a Microsoft Windows operating system installation by executing two processes: a) initializing the drive and b) copying system files to that drive in order for the operating system to be run locally (see Volume).
The early versions of Windows required an existing compatible version of DOS operating system in order to be installed. The Windows NT family, from 3.1 through 6.0 featured text-based installation that prompted users to a GUI wizard in the final steps. The 9x family installer was similar to NT despite it being MS-DOS-based. Additionally, it did not need preinstalled DOS as a requirement. With the release of Windows NT 6.0 (Vista), Microsoft introduced a fully graphical setup environment after dropping MS-DOS backward compatibility from Windows.

The installation of Windows 1.x, Windows 2.0, Windows 2.1x requires that a compatible version of MS-DOS is installed. The user must specify any hardware such as mice or printers during installation. After the installation, Windows was to be started either manually by typing "WIN.COM" at the command prompt, or configured for automatic startup by adding WIN.COM to the end of AUTOEXEC.BAT.

The installation of Windows 3.0, Windows 3.1x and Windows 3.2 requires that a compatible DOS operating system is already installed. The installer attempts to detect network cards, mice, and other hardware on its own but will rely on the user to specify hardware if it cannot find them. After the installation, Windows was to be started either manually by typing "WIN.COM" at the command prompt, or configured for automatic startup by adding WIN.COM to the end of AUTOEXEC.BAT.
