Windows XP was released by Microsoft in 2001 and became one of the most widely used desktop operating systems of its decade. Its logon chime formed part of a small set of system sounds heard daily in homes, offices, and schools, alongside clicks, alerts, and the shutdown melody. As XP was retired and replaced, recordings of its sounds circulated on video platforms and meme edits as shorthand for an older internet era. It remains popular because even listeners who never used XP recognise it instantly as the sound of a computer starting a session.
