|Sadfully this is a common problem even after installing the latest service pack (SP2) manually.|
I have installed a lot of machines with Vista and experienced the same behaviour when I was trying to update them.
However, this annoyance when updating Windows does not only apply to Vista but also to newer Windows versions like 7 of 8.
With Windows XP there are some difficulties too, but they are easier to overcome than update problems with Vista or later versions.
That was for the bad news, but I also have good news, because eventually all the machines will update!
Whenever you see the "Install Updates and Shutdown" dialog box, it's good news because it will apply (at least some) updates.
In the end you will have updated just enought to receive all other updates normally
Bad news however it that it can take more than a week before the problem will resolve itself...
