The Windows 95 startup sound comes from Microsoft's Windows 95 operating system, released in 1995. The chime was composed by Brian Eno and was designed to match the system's new, welcoming feel. Over time, it became one of the most recognizable computer sounds ever made. Online, it spread through retro computing videos, nostalgia compilations, and meme edits that use it to instantly suggest old PCs, early internet culture, or a fresh digital beginning.
