Happy Birthday Windows OS!

The Windows 1.0 desktop

On November 20, 1985, Microsoft shipped Windows 1.0. It’s, rather than typing MS‑DOS commands, you just move a mouse to point and click your way through screens, or “windows.”
Bill Gates said, “It is unique software designed for the serious PC user…”

The fully-packaged Windows 1.0

There are drop-down menus, scroll bars, icons, and dialog boxes that make programs easier to learn and use.

You're able to switch among several programs without having to quit and restart each one.

Windows 1.0 ships with several programs, including MS‑DOS file management, Paint, Windows Writer, Notepad, Calculator, and a calendar, card file, and clock to help you manage day-to-day activities. There’s even a game—Reversi, in color.

Windows is going as strong as ever.
