Microsoft released Windows 95 in 1995, and its startup sound was composed by musician Brian Eno, who was asked to create a short piece that felt welcoming, optimistic and futuristic. The brief melody played every time the system booted, making it one of the most heard sounds of the decade as home computers spread. Decades later it survives through retro computing videos, tech nostalgia compilations and meme edits, where it instantly signals the 1990s and the excitement of switching on a personal computer for the first time.
