Back in the day, every time you installed Windows or a piece of Microsoft software, you had to click “I Agree” on the End User License Agreement—the EULA—before you could do anything. Microsoft’s EULAs started showing up big-time in the early ‘90s with Windows 3.1 (1992) and kept evolving through Windows 95, 98, and XP, laying out what you could and couldn’t do with the software—like no sharing copies with your buddies or hacking it apart. By Windows 2000 and XP, the EULA had gone digital, popping up during setup instead of being buried in a manual. It wasn’t flashy, but that wall of text became a rite of passage for anyone loading up Office 97 or firing up a new PC, a small but unforgettable part of the home computer experience.
