Move over, MS-DOS. On November 20, 1985, Microsoft released version 1.0 of the graphical desktop operating system known as Windows
, and the world of computing changed forever. Over the next 30 years, the industry would see 19 significant new versions of the now-ubiquitous OS released, and that's not even counting bizarre offshoots like Windows RT
or Windows 10 for IoT devices
In honor of this milestone anniversary, let's take a look back at Windows' major revisions through the ages. Special thanks to GUIdebook
