Vista Enterprise and Windows Update problems

Can't figure this out.

We use a GPO to prevent anyone from running Windows Updates, we accomplish
this via WSUS.

I recently received an icon in the taskbar that suggests I have updates to
install. So I double click the icon, it then opens the Windows Update window
within Vista and I do not see any updates in which I can install.

Check for Updates is greyed out like it should be.

When I open 'Change Settings', I'm able to select which ever option I'd like
to - which is supposed to be disabled according to how the GPO was setup.

And yet, I still cannot find where I need to go to install the available
updates.

Any suggestions??
