Windows XP : end of support
After 12 years, support for Windows XP ended 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 ended on April 8, 2014.
