The clip is labelled as the hardware remove sound from Windows 8, the Microsoft operating system whose familiar system tones accompanied everyday tasks such as plugging in and unplugging USB drives, mice, and phones.

It remains useful today because the sound needs no explanation: one descending pair of notes tells a viewer something has just been disconnected.
