Microsoft Windows 3.0 was first released on May 22nd, 1990 – 18 years ago today.

The operating system came on seven 3.5″ disks and required a 286 processor and a whopping 640K of memory. It also required that you already have DOS 3.1 installed.

It came with a text editor called Notepad and a word processor called Write. It also was the first version to include Solitaire.

Windows 3.0 went on to sell over 10 million copies.

Sure, Microsoft ripped off lots of stuff from Apple’s OS, but Apple stole a whole bunch of ideas from the Xerox Star including “graphical user interface, icons, folders, mouse, Ethernet networking, file servers, print servers and e-mail.”

If you’ve never had the “pleasure” of working with Windows 3.0 – be thankful. It was horrible. But it was an important step in the process.
