Well, let's take a look
The last 3 critical updates I show in Add/Remove (I just updated a few minutes ago) reflect KB961371...KB971633...KB973346. There were two additional updates, one of which was the Malicious Software Tool...but neither of these show up in A/RP.
What are the last 3 that show on your system in A/RP?
I suspect that something did not install properly...which may be why the repetitive attempt occurs.
One other thing that I suggest...is a manual visit to Windows Updates. Something may be wrong with the automatic download/install feature of XP, but a trip to Windows Update site will reveal if you are missing any critical updates.
