Windows 11 was released by Microsoft in October 2021 as the successor to Windows 10, bringing a redesigned interface and a new default startup sound. The chime was designed to feel lighter and calmer than previous versions, reflecting the system's softer visual design. Clips of the sound spread through tech channels, tutorials and soundboards as users recorded their first boots and clean installs. It remains widely reused online as an instantly recognisable cue for a computer starting, updating or being switched on for the first time.
