Windows XP and Office 2003 will be discontinuing support as of April 8, 2014
As good as Windows XP was, it’s 10 years old and Microsoft is discontinuing support so they will focus on Vista, Windows 7 and Windows 8 and who knows what’s yet to come. Same with the 2003 version of Microsoft Office. You can see the link below for details straight from Microsoft.
If you are running a business with XP computers or Office 2003 suites, you will need to seriously plan your budget for replacing them all asap. After this magic date, everything will still work, but the thing is if something goes wrong, you’re screwed. More importantly, things may look ok but you are not getting anymore Windows or Office updates which puts you at risk of viruses and hackers. Plan for replacements in advance.
