Let me introduce you to Linux. A free Operating System that can replace Windows for a very good fee. FREE. Yes you heard me...FREE, NADA, ZIP, ZERO, ZILCH! What is the catch? Well you may have to give up a few things like native gaming but even that is a minor point.
Linux is an Open Sourced OS. It is very resistant to virus' and there is next to no spyware that will work on Linux. You will save money by not needing an Anti Virus Program and the same holds true for Spyware Programs. It is very easy to use and you can tailor it to YOUR needs and not to the needs of others. Let see Windows do that.
There are multiple versions of Linux. Each one is called a Distro which is short for Distrobution. The most favoured are PCLinuxOS, Ubuntu, and Arch Linux. Each is unique is multiple ways and each distro will allow you to run from a CD or DVD without having to install. This is called a LiveCD or LiveDVD. Think of it as Try Before You Buy.....but in this case it is free.
