On this training you will learn the Zorin Operating System is a personal computer operating system designed and promoted for users new to Linux-based computers. One of its built-in features lets users change the interface to resemble those of Microsoft Windows or macOS. Wine and PlayOnLinux can be easily installed in Zorin OS, allowing users to run compatible Windows software for ease of transition. Zorin OS's creators maintain three free-of-charge editions of the operating system, and a "Pro" edition for purchase.

The current releases are Zorin OS 16 Pro, Zorin OS 16 Core, Zorin OS 15.3 Lite, Zorin OS 15.3 Education and Zorin OS 15.3 Education Lite. The new editions continue to use the Ubuntu-based Linux kernel and GNOME or XFCE interface

Zorin OS is fully graphical, with a graphical installer. For stability and security, it follows the long-term releases of the main Ubuntu system. It uses its own software repositories as well as Ubuntu's repositories.

Zorin OS was initially released 1 July 2009. Earlier versions required users to do a clean install, but since version 12.4, the system's update manager can be used to upgrade existing installations.

Zorin OS has been praised for its intuitive and familiar layouts, functionality, and installation process; as well as for making it easy to use a Windows-similar layout, install NVIDIA drivers, and navigate an easy and intuitive software center.
