Windows XP was released by Microsoft in 2001, and its short startup chime became one of the most recognisable sounds of early home computing. It played as the system finished loading, welcoming users to the colourful Bliss desktop that defined the era. As XP machines were replaced, the sound lived on through YouTube compilations, remix videos and nostalgia content, where it now signals the early 2000s instantly. It remains popular because it captures a time when personal computers were becoming a fixture in homes, schools and offices.
