Microsoft first released Windows XP on October 25, 2001 and after over twelve years of supporting the operating system announced it is ending Windows XP support April 8, 2014 which means that they will no longer be providing any updates, patches, or further software security related support.
If you are still running Windows XP it will continue to work after this date, but if a security vulnerability is discovered after this date it will not be fixed by Microsoft....
