The shutdown jingle comes from Microsoft Windows XP, released in 2001, where it played alongside the startup melody and the error sound as part of the default system scheme. The clean, friendly chimes became instantly recognizable to a generation of PC users. In the 2010s, edited versions began circulating on YouTube and meme pages, with creators boosting the bass for comic exaggeration, similar to other distorted notification sounds. It remains popular because the melody signals an ending in one second, and the heavy boost turns that nostalgia into a punchline.
