The Zorin OS team is proud to release Zorin OS 6 'Core' and 'Ultimate', the latest version of our operating system designed for Windows users and those who are dissatisfied with the Unity and GNOME Shell offerings. At the core of Zorin OS 6 lies our new and unique desktop environment named 'Zorin Desktop'. We also include our innovative Zorin Look Changer which allows users to choose between the Windows 7, XP and GNOME 2 graphical interfaces in Core as well as the Mac OS X, Unity and Windows 2000 interfaces in Zorin OS Ultimate. Zorin Desktop embraces all of the latest and greatest open-source software and technologies such as GTK+ 3 and other software applications from the GNOME 3 software stack, all without affecting the familiarity, usability and customizability of the desktop and retaining the Compiz window manager.
