Jade

Jade is a visual style introduced in Windows Longhorn build 4066 up to build 4093. Jade is a DWM theme, forked from the private DWM theme Aero. The name Jade came from the appearance of its DWM resources (green and translucent). Being a fork of the Aero theme, Jade differs from the private Aero theme in a few aspects, namely DWM resources,,   and possibly the Preview Pane Aurora. Although Jade can be used to reconstruct the Aero theme, contrary to popular belief,  renamed to   will not give you the private Aero theme.
