(K Desktop Environment) A GUI-based user interface primarily for Unix and Linux machines, but also available for Windows and Mac. The source code is freely distributed and is maintained by developers around the world. Lindows uses KDE for its Linspire (Linux) desktop and has changed many of the defaults to make it look more like Microsoft Windows, which most everyone is familiar with. When KDE is used with Ubuntu (Linux), the combination is called "Kubuntu" (see Ubuntu). For more information, visit www.kde.org. See GNOME.
