A friend of mine has a desktop PC running XP Home 2002 SP2 and has a re-occuring Windows update icon in the system tray. I have followed the link to install it about 4 times now. It doesn't ask for the pc to be re-booted but on two occations I have re-booted anyway. It says its a MS service pack 1 update even tho this pc is SP2. It says the update install OK but then the icon re-appears in the system tray moments later and you have to run thru the whole thing again.
