The chime comes from the Windows Vista era, when Microsoft's operating system used a new set of short system alerts for everyday hardware events. Vista had been developed under the codename Longhorn, which is why some copies of this clip still circulate with that name in their file tags. As old PCs were recorded, ripped and reposted on soundboards, the insert tone joined the error sound and other familiar Windows noises that editors reuse. It survives because listeners recognise it instantly, even without seeing a computer.
