Windows 95 Plus! Themes dropped in 1995 as part of the Microsoft Plus! pack—basically a $49.95 upgrade for people who wanted to flex their setup beyond the basic Windows 95 install. It came with a handful of built-in desktop themes like “Inside Your Computer,” “Science,” and “Space,” each with its own custom wallpapers, sounds, icons, and screensavers. Nothing crazy by today’s standards, but back then? It was the first time most people saw their PC look personal. Microsoft kept the idea going with Plus! 98, and even Plus! for Windows XP. This was peak late-'90s digital vibe—cheesy MIDI sounds, pixel art icons, and starfield screensavers that made your beige tower feel futuristic.
