Repeated Update Install

Hi,

There are 3 updates that repeat install everytime I turn my computer on. 2
of them install during shut down and 1 during boot up. Always the message is
'installing update x of 3 (xx%)'.

How do I find out which updates are trying to install every time, and how
might I go about getting rid of this problem?

Thanks for any help!

Solved. Seems the updates were for Office 2007. I had a trial version ship
with the computer and updates for it were causing issues. Removed the Office
trail and sub-sequently the Office updates were removed also. This solved
the problem.
