Windows 10 build 10074 was an Insider Preview build released by Microsoft in April 2015, ahead of the full Windows 10 launch that summer. Its notification chime became part of the familiar set of system sounds users heard for messages, reminders and app alerts. Clips of the sound later circulated on soundboards and in editing packs alongside the Discord Notification and a classic ding sound effect, where creators reuse it to imitate a real PC alert or to add instant tech context to a joke.
