On April 8th, 2014, Microsoft is officially ending extended support for the Windows XP operating system and extended support for Office 2003 will also end on this date. Microsoft will discontinue security updates for both Windows XP as well as Office 2003 at that time.
This means that vulnerabilities in the software will no longer be patched, and systems which have not been updated will be left open to exploits, malware, spyware and viruses. Once support ends Anti-virus software will not be able to fully protect systems which are still running this unsupported software.
Our recommendation is that all XP systems which meet minimum requirements are upgraded to Windows 7 Professional. If minimum system requirements are not met then you should consider replacing affected systems with new hardware and a downgraded Windows 8.1 Professional license installation of Windows 7 Professional.
Unfortunately there is no direct upgrade path from Office 2003 to the latest version of office as Microsoft Office 2003 installations need to be replaced by Office 2010 or Office 2013.
Looking down the road Microsoft will officially end Windows 7 general support (patches and fixes) on Jan. 14, 2015, however security patches and fixes support will not end for Windows 7 until 2020.
