These tones come from the system sounds built into Microsoft Windows 11, released in 2021, which play automatically when hardware is connected, removed or fails to be recognised. Because almost every Windows user has heard the USB plug-in chime at some point, the sounds became a shorthand in tutorials, tech reviews and online videos for showing a device working, dropping out or going wrong. The short error sound in particular is now widely reused as a comic cue for a failed attempt, keeping the clip useful long after its original operating-system context.
