Windows 7 was released by Microsoft in 2009 and its startup sound became one of the most recognisable system sounds of its era, heard daily in homes, offices and classrooms. The short melodic chime was designed to feel welcoming as the computer loaded to the desktop. As Windows 7 remained widely used for many years, the sound stayed familiar long after launch. Online it survives in meme edits, nostalgia compilations and parody reboot scenes where the chime signals a person or machine starting up again.
