WGA: downloaded but not yet installed

Hi All,

I have been trying to avoid Windows Genuine Advantage notifications on
my Windows XP machine. I'd thought I'd refused it when I was offered
it by the Windows Update site and that was the end of it, however I am
clearly somewhat naive. Now I am at the stage where the windows
updates website tells me that it has been downloaded but has yet
installed. So is there anyway I can delete it from the installation
queue? At present I'm just not clicking on "install", but I can't
carry on doing that when other updates come along that I do want.

Here's a screenshot if it's any use: http://www.theimageplace.net/webpage/4cec956b02.php

Cheers!
