Windows 8 build 8400 was the Release Preview made public in May 2012, the last preview before the final Windows 8 release that October. Its tada sound belonged to the default Windows sound scheme, a set of short chimes for logons, notifications and completed actions. As old builds were archived by enthusiasts, the individual files were ripped and shared on forums and soundboards. It sits alongside other system cues like the error sound and the ding sound effect in soundboard collections, kept alive by nostalgia for early Windows 8 testing.
