Windows 10 was released by Microsoft in 2015, and its notification sounds were included as WAV files in the Windows Media folder on the system drive, where users could find and reuse them outside the operating system. The Notify chime spread through tutorials, tech forums and soundboards as people extracted the file for projects and pranks. Because so many computers used the same default, the sound became a shared shorthand for a system event, and creators still use it when they want an alert that any PC user will recognise instantly.
