Windows XP launched in 2001 and its small system sounds became part of everyday computing for millions of users through the 2000s. The ding was used for default alerts and information pop-ups, so it was heard constantly at home, school and work. As XP aged, recordings of its sounds circulated on video sites and soundboards as nostalgia grew. Editors kept reusing the ding because audiences recognised it instantly without explanation, turning a plain operating system alert into shorthand for an error, a warning or a retro PC moment.
