User Account Control was introduced by Microsoft with Windows Vista to stop programs making system changes without permission, and its alert sound became a familiar part of using Windows through Windows 7, 8 and 8.1. Windows 8.1 arrived in 2013 as the update to Windows 8, keeping the same prompt and chime that many users heard daily. Online, the sound spread through tutorials, prank edits and meme videos recreating PC popups, and it is now reused as a generic error sound for blocked actions.
