So I saw the news items about the new security issues in Office and went to update my home install via office update. Unfortunately you need office SP2 to install the patches and you need your original install media to install SP2. I just moved. I have no idea where the original media is. How many people out there are in the same boat? What if someone (gasp) pirated their copy of Office?
Requiring original media to install security updates seems like a bad plan to me.
