Windows Media Center was Microsoft's living-room media application, included with some editions of Windows 7, which was released in 2009, and it let users browse television, recorded shows, music, photos and DVDs from a couch-friendly interface controlled with a remote. Its startup sound became familiar to anyone who used a home theatre PC during that period. Years later, clips of the sound circulated on soundboards and in retro technology videos, where it now works as a quick shorthand for Windows 7-era computing and early 2010s home entertainment.
