Microsoft released Windows 95 in August 1995, and its startup sound was composed by Brian Eno, who was asked to create a short piece that felt welcoming, optimistic and futuristic. The resulting few seconds became one of the most recognised computer sounds in the world, heard by millions as personal computers entered homes and offices. Decades later it circulates widely in nostalgia videos, retro tech channels and memes, where its familiar rise instantly signals the nineties and the early days of home computing.
