If you're still using a PC running the Windows XP operating system, be aware that you may be running out of time. Microsoft has publicly stated that the end of life for Windows XP is April 8, 2014. That does not mean that your PC will stop working on that date, it simply means that support will start getting increasingly difficult to obtain. The OS will be locked which means what you have is what you get. Patches and bug fixes will disappear and when the security updates stop coming your PC will become much more susceptible to new virus’s and harmful malware. There's still time, but replacing Windows XP should definitely be put into the budget.
