The sound is part of the default sound scheme introduced with Windows 10, released by Microsoft in 2015 as the successor to Windows 8.1. Its notification chime was designed to be less intrusive than earlier Windows alerts while still being clearly audible over speech and media. As Windows 10 spread to hundreds of millions of PCs, the chime became a shared reference point online. Creators reuse recordings of it in memes, fake update screens and software tutorials, where its familiarity instantly signals a computer alert without needing any explanation or on screen text at all.
