First off you can try a System Restore. This will remove the updates IF it will restore.
Try the one made just before the updates were installed. This one will be made by the updater and it will be first in the list.
As in this Snip below if the 11/18/2010 update had been a problem. I could have tried all three of the top 3 Restore points listed.
I would have tried the top in the list first.
Did you try the reset?
Try this second and see if it fixes problem.
When done with reset check the list of Installed Updates and see if they are showing. Windows Update - Reset
If the reset does not prompt a reboot and the Installed Updates list is still empty. Reboot and check it again.
It may have to add them back into the list on Boot.
I'm making no guarantees but neither of the above actions will hurt anything.
