windows updates "failed"

-----Original Message-----
When viewing the installation history on the windows
update page I noticed this. There is a critical update
that was successfully installed on my computer on Feb,
27. The installation history says that that same
critical update, which was successful on the Feb 27,
failed to download on the March 4, and that it also
failed to download on March 23 and many other later
dates. How come it downloaded successfully the first
time, but every other time it attempted to download it
has failed? Many of the other updates on my computer
are
the same way. They download the first time
successfully,
but then on every other later date, it says that
installation failed. Can you explain why this is
occuring? Are updates installed every day? It seems
like
my computer is downloading updates everyday, including
new ones that are successful, and updates that were
previously downloaded successfully but failed this time.
.
I've been having exactly the same problem with critical
update 814033 which is supposed to ensure that updates
are successfully installed. According to my installation
history this update was successfully installed on March
20 but every day since them automatic update advises me
that it is available for installing and the installation
fails when I try to do it.

Any suggestion anyone ?
