Twenty-five years ago this month, Microsoft released an extension to its Disk Operating System (DOS) that gave users a graphical, mouse controlled environment with which to interface with their computers. Bundled with the new setup were a few applications like a drawing program, a simple word processor, an appointment calendar and a clock. Each program could be launched in its own box - or window - and tiled around the display screen. It wasn't a noted success but marked the start of a technology snowball that sees Windows currently being used on nearly 90 per cent of the world's computers.
