John,
I have often found this but, it does no harm.
It is just a fact that, sometimes, the shield icon just disappears when
it should remain so you can click on it to install the Updates straight
away. After downloading completes, the icon sort of "flickers" and then
is gone.
I don't know if it caused by some inability to complete all the
downloads as described in the google.groups post cited by "P.A.Bear", or
not.
But, conversely, if the icon remains in the taskbar, but you ignore it,
on turning off your PC you will also find the "shield" displayed on the
shutdown icon as you described.
So it is a "normal" feature.
However, I have found that, after the download completes and if the
shield disappears, typing :
wuauclt.exe
...into the "Run" box and then after waiting a few moments.
The icon should then re-appear in the taskbar again...
You are then able to click on it to install updates immediately

PABear is correct when he relates this issue's cause to all of the
updates not being downloaded. MS is aware of this issue as we've
submitted numerous WindowsUpdate.logs that show a system ready to
install updates on Shutdown but the update icon does not appear prior to
Shutdown because 1 or more NON-security updates have not been downloaded.

Extended Protection for Authentication
http://support.microsoft.com/kb/968389
Why this update is considered non-Security content when the KB article
clearly states
This security update modifies the SSPI in order to enhance the way Windows authentication works so
that credentials are not easily forwarded when Integrated Windows Authentication (IWA) is enabled.
is beyond my comprehension -
