After 12 years, support for Windows XP will end on April 8, 2014. There will be no more security updates or technical support for the Windows XP operating system. It is very important that customers and partners migrate to a modern operating system such as Windows 8.1. Customers moving to a modern operating system will benefit from dramatically enhanced security, broad device choice for a mobile workforce, higher user productivity, and a lower total cost of ownership through improved management capabilities.
Support for Office 2003 also ends on April 8, 2014.
Tomorrow should be interesting as you can be assured there is numerous exploits and vulnerabilities the bad guys are just waiting to use. If you are still using XP it's probably time to consider upgrading to at least Windows 7. Site stats indicate about 10% of the people that visit here are still on XP.
