From 8th April 2014, Microsoft will no longer be supporting Office 2003 and Windows XP. See https://www.microsoft.com/en-gb/windows/endofsupport.aspx for more details. If you continue to use Windows XP, you are more likely to be less secure to hackers, etc..
If you are still using these versions, it might be time to consider either moving to Windows Windows 10 and either Microsoft Office 365 or Microsoft Office 2016.
