Security
On April 8, 2014, Microsoft will stop supporting Windows XP and will no longer issue security patches and bug fixes for Windows XP. This will make computers running Windows XP vulnerable to malicious attacks and malware. For this reason, we strongly urge all Windows XP users to upgrade to Windows 7 or 8.1 by April 8.
