On April 8th 2014 the extended support period for Windows XP and Office 2003 will finally cease. No more security updates, no more paid support, 3rd party support will end, dead.
If you are still running and supporting Windows XP or Office 2003 this is pretty bad news. If your organization has any form of IT Security or Privacy Compliance to deal with (PCI DSS, HIPAA, SOX etc) this is really bad since it could put you out of compliance and facing the threat of fines or worse. To be clear this isn’t a small problem either, Feb 2013 browser stats suggest between 22.59% and 38.99% of PCs were still running Windows XP.
