Vista - 1 Vista Update does not install

First, a bit of background.

I purchased the Vista system in May 2008.
Last ran a Windows update on 21 June 2008.
Why?
Because the first time I ran a Live Update with NIS 2008, my wireless connection broke.

So, I decided to not do anything significant, on the internet, until I got rid of NIS 2008 and replaced it with something better, KIS 2008. I did this yesterday.

So, I ran a Windows update last night. As it had been 10 months, there were about 379MB of files. Since I am still on dial-up (expect to switch to broadband after I straighten out this update issue, hopefully, next week), I let the critter run overnight.

Alas, when I awoke, I found the 'puter wating for my response to the question of whether I wanted to upgrade from IE 7 to IE 8. Due to the inactivity, I was logged off by my ISP.

Today, I ran several updates, until I finally got to an update that indicated that there was only 1 optional update remaining. However, this update will not install. Any ideas why?

The following are the details.
P.S. Error code was 80070103 Windows Update Encountered am Unknown Error

Hi Howard, This error code is nothing to worry about. It means that the optional update driver is either already installed on your system, or that it is not as new as the already installed driver.

Did the other updates (IE8) finish installing?

Pooch

Probably, but then why did not Windows Update silently bypass this install?

Appears so.

I had to go thru several iterations.

I expect that a lot of updates did not install because they were superceded by other updates.

That's just the way it works but its not hard to live with.

You can check here, Type update in the Start Search, Click on windows update.Ink.
In the new window, if it says "Windows is up to date" then you are finished. If not just follow the instructions to install available updates

Hi pooch just a small correction, its windows update.lnk

Ok............. I'll watch my speeling next time

Ayup.

When I first ran Windows update, IE 7 has present.
Later, I installed IE 8, which required more updates.
I iterated several times until I got the error about RealTek.

It will be interesting to see what occurs next time I run Windows Update.
