PCLinuxOS is a free easy to use Linux-based Operating System for desktops or laptops.
PCLinuxOS is a Linux distribution designed for ease of use on desktop and laptop computers. It pioneered the concepts of supplying a Linux distribution on an installable Live CD. You can boot from the CD and try it out - make sure your hardware is recognised and you like the way it works - without installing anything or affecting the other operating system(s) on your computer. Then you just click the Install icon, answer a few simple questions and the full operating system is installed to your hard disk along with a complete suite of desktop software.
As with most Linux distributions, this is a lot more than an operating system, it includes software you would have to add on with other OSes. Not only does it contain a full sets of Internet software: browser, mailer, IM clients and social networking software, it also comes with music and video programs, digital photograph management and editing and a complete office suite.
There is also plenty of other software, a CD only holds so much, that you can install from within PCLinuxOS once it is running on your computer. You can even create a new live CD (or DVD) once you have things set up as you want, ready to install a similar system on other computers. No matter how easy to use a system can be, there are always times you need help, and there is plenty of this available on the PCLinuxOS forums, where developers and other users are always willing to help. There is even a monthly downloadable magazine to help you get the most from it.
