Microsoft introduced Windows 8 in 2012, with Windows 8.1 following in 2013 as a free update that refined the new Start screen and desktop experience. The startup sound heard here was the short audio cue played when the system finished loading, replacing the longer, more orchestral themes used by earlier versions of Windows. As older computers were replaced, the sound became a marker of early 2010s technology, shared in nostalgia videos, retro computing clips and soundboards. Creators still use it today because it immediately signals a familiar era of PCs without needing any explanation.
