Windows 7 was released by Microsoft in October 2009 as the successor to Windows Vista, and its startup chime was built into the default sound scheme played during boot and login. Unlike earlier versions, the sound became closely tied to an era when Windows dominated home and office PCs. As those machines aged, clips of the chime spread on YouTube and social media in nostalgia edits, often paired with the error sound in memes about crashes and restarts. It remains popular because it instantly marks a specific generation of computing.
