This clip is labelled as the notification sound from Windows 8 build 8400, one of the preview builds of Microsoft's Windows 8 operating system from the early 2010s. Preview builds were shared with testers before the final release, and their small system sounds were later saved and uploaded by collectors of retro computing audio. Because it is so short and unobtrusive, it still appears in soundboards and edits that recreate old desktop environments or poke fun at dated technology.
