KB938979 fails to install

I cannot get KB938979 installed. What I find strange about it is, after it
installs, it asks to reboot like any other update does. Windows Update says
it completed successfully. Then when I reboot, it comes up to the
Configuring Updates screen....then says restarting computer again...weird.
After it reboots the 2nd time, it says Configuring Updates again, then lets
me log back in. When I do and check the Update History, it says the update
failed. I am taking a guess here, but it almost seems like it is attempting
to apply the update, runs into a problem, then reverts the changes and
reboots the 2nd time.

Here are the error details:

I have looked up error code 800F0826 which says:

===================
Windows Update error 800f0826 is displayed when an update for Windows has
failed to install and is preventing you from installing additional updates.
Error 800f0826 does not identify the update that has caused the problem. The
update that has caused the problem will display a different error. This
problem affects updates for Windows only and does not prevent you from
installing or automatically receiving updates for other Microsoft programs,
such as the Microsoft Office System.

To prevent error 800f0826, you need to identify the update that is causing
the problem (it will display a different error), fix the problem, and then
try installing updates again.
===================

This is the only update I have that fails. So there is no other causing a
problem. Now I was having a problem with another update but I was able to
install in manually on 12/24 and it fixed the problem. That update was
throwing the same error code though.

I have tried the manual update with KB938979 as well, but has the same
results as the automatic update. I am completely lost as to what to do to
get this installed.
