Startup chimes have been part of the Microsoft Windows operating system since its early versions, playing automatically after boot as confirmation that the desktop was ready. Because Windows ran on most home and office computers for decades, the melody became one of the most recognized computer sounds, alongside an error sound or a ding sound effect. Online, creators reused recordings of it for memes about starting, loading and rebooting brains or devices, turning a routine system cue into a nostalgic shorthand that still lands instantly with anyone who grew up using PCs.
