MS support for the 2007 product has ended.
Hmm, I have MS Office 2007 installed on a desktop system (Win 7) and my laptop (Win 8.1) and I still get updates for Office along with Windows Updates almost every time Windows Updates occurs.
In addition to minor updates, Microsoft releases special/major updates, i.e. "service packs", for MS office, just as they do for Windows. I suspect that edition of Office you found is an original release of Office 2007; in other words, it will not have any of the Service Pack (SP) updates. If you get the Office disc and install it, the Service Pack update(s) might appear in Windows Updates. If not, you can download any of the Service Packs, i.e. 1, 2, or 3, from

By the way, the Publisher component works fine.
