Windows 7 was released by Microsoft in 2009, and this short chime was part of its default sound scheme, greeting users each time they signed in to a computer running the system. As Windows 7 became one of the most widely used versions of Windows, the sound became familiar to a whole generation of PC users. Years after newer versions replaced it, clips of the chime spread in nostalgia videos, retro tech edits and memes about old computers, where it still works as instant shorthand for the late 2000s PC era.
