On April 08, 2014, Microsoft support for Windows XP ended. Windows XP is a 12 year old operating system. There will be no more security updates or technical support for windows XP and on the same day support for Office 2003 also ended. It is important that we upgrade our operating system to a modern version, such as Windows 7 or 8.

WHAT DOES THIS MEAN?
If you are still using windows XP, it will leave your computers vulnerable to hackers, viruses, and other security risks, because Microsoft will no longer be providing technical assistance and critical updates for users of Windows XP. It is strongly recommended that users upgrade to a new version of Windows in order to benefit from enhanced security, broad mobile device choices, and higher user productivity.
