Windows 7 was released by Microsoft in 2009, and its logon sound became part of the everyday soundtrack for millions of home and school computers during the following years. Unlike a generic notification, it was tied to the moment a user signed in and reached the desktop, so it quickly became associated with starting a session. As Windows moved to newer versions, the chime lived on through nostalgia videos, operating system comparisons and retro computing channels, where it instantly signals an earlier era of personal computing.
