From Wiki96
The JS Certified "Developer" Wallpaper is one of the oldest wallpapers on Windows 96, along with the Harold Wallpaper. It features a yellow background, a giant "JS" in the font of the JavaScript logo, and pixelated text stacked on top of each other saying "Certified 'Developer'".
It has been included in Windows 96 since the release of V0.1 and can still be found in the current version of Windows 96.
