Make sure you reboot your machine to fully complete any updates, and then check that there aren't any other updates pending.
I find it a good idea to do the same thing when manually updating my anti-virus software: do an update, then keep attempting to update again until it comes back with a "not required" message (or equivalent).
(As an illustration: I've just gone and attempted a manual update to my anti-virus software, and although it last did an automatic update only 4 hours ago, there were 4 updates waiting! I think we can presume that the anti-virus guys are being kept very busy at the moment... )
