I'm not at the machine right now, but running winver very clearly reports "sp3" and "Service Pack 3" in the output.

If not, you can download SP3 here and then run it.

Been there, done that. That's the problem. Windows Update still refuses to run, redirecting the machine back to the Microsoft pages with instructions to download/install sp3. I don't think they tested this combination.
