On the other hand, basically everybody who had an opinion about Windows's design used the official terms

- Windows XP: Luna; see https://en.wikipedia.org/wiki/Windows_XP_visual_styles

- Windows Vista, 7: (Windows) Aero: see https://en.wikipedia.org/wiki/Windows_Aero and Liquid Glass (though the latter is an Apple term): https://en.wikipedia.org/wiki/Liquid_Glass

- Windows 8, 8.1: Metro; see https://en.wikipedia.org/wiki/Metro_(design_language)
