Zorin Linux 6.0 is a very capable replacement operating system for Microsoft Windows. It is also a bother-free alternative to other Linux distros that suffer from the usability issues of the Gnome 3 or Ubuntu Unity desktop interfaces.
The Zorin Linux distro is an offshoot of Canonical's Ubuntu Linux but it has much more of the look and feel of Linux Mint with a few very substantial differences. These make Zorin an ideal choice for Windows users and others who dislike having to learn a new approach to computing.
