The startup melody was composed by Brian Eno for Microsoft and introduced with Windows 95 in 1995, when millions of home computers played it daily at boot time. Eno created a brief, optimistic piece that became one of the most recognisable computer sounds ever made. As the operating system faded, the chime survived online in retro compilations, memes and videos alongside the classic error sound. It remains popular because even listeners who never used Windows 95 recognise it as a symbol of early personal computing and internet culture.
