Windows 7, released by Microsoft in 2009, shipped with a short, gentle startup chime that millions of computer users heard every day, making it one of the most recognisable sounds of that era. As bass-boosted remixes became a popular meme format online, creators began applying the same heavy low-end treatment to the Windows chime, turning a calm system sound into a loud, comedic punchline. The boosted version spread through short videos, edits and soundboards, where it is still used to signal nostalgia, a dramatic entrance or an over-the-top reveal.
