As of April 8, 2014, Microsoft no longer supports Windows XP. Windows XP has reached its End Of Life. What does this mean? It means that Microsoft will no longer provide security updates or technical support for Windows XP. PCs running Windows XP after April 8, 2014, will still function, but they should not be considered safe from hackers, viruses, and malware. Read more below:

Desktop Linux is a viable repacement for Windows XP. If you are ready to bring new life to your older computer, a Linux Operating System is a fast, easy to use option that will be supported for years to come. There are several "distros" (flavors of Linux) from which to choose, and there is one that is right for you. With a Desktop Linux Operating System you will no longer have to worry about viruses and malware, since (like it's cousin the Mac OS) a Desktop Linux OS is inherently more secure than Windows. Best of all, Desktop Linux is FREE and comes loaded with FREE software; and Desktop Linux has access to hundreds of FREE programs. You have everything to gain and nothing to lose by exploring a Desktop Linux Operating System as a replacement for your now defunct Windows XP OS. Learn more about Linux below:
