"Many people coming from Windows try Ubuntu Linux as
their first Linux distribution. But Ubuntu itself, while very good,
may not always be the best choice. There are many Ubuntu
derivatives and it's possible that one of those can sometimes be a

Linux niche. Zorin OS is an Ubuntu derivative designed to help make
the transition from Windows to Linux as easy as possible.
"Zorin OS 4 is the latest release. Zorin OS comes in a number of
Zorin OS Core
Zorin OS Lite
Zorin OS Gaming
