One would hop that they would only not provide new patches. Not actively block them from the platform. I would expect MS Office to keep getting update. For example.
Office? I guess you mean Office 2007 or newer since Office 2003 was EOL'ed with XP. To that end, I agree, Office 2007 updates should definitely run on XP or there should be hell to pay. But since you can't get support for XP any longer I could see MS saying - if it doesn't work, we're sorry we can't help you until you are on a supported base platform as XP is no longer considered a supported platform for Office 2007 or 2010.
