Do you happen to know the situation as well? No matter how often you install Windows DreamScene it keeps reappearing as a "new" update?
However the solution is easy: first uninstall it (Control Panel > Software > Installed Updates) and rerun Windows Update.
Now install it once more and it should not appear again (but instead you'll see the content packs with more "dream scenes" [2]).
Enjoy!

Usually I try to blog things that interest many people, but there are some cases where the audience is knowingly extremely small, but nevertheless these people will be very glad to have found a solution to their problem.
If you own a Dell Dimension 9xxx and install Windows Vista, which at least in my case is not officially supported, but Dell Support did a very good job in helping me out, and your system periodically freezes (music stops etc.) and after approximately 30 seconds it's like is has never happened and after 2 or even 10 minutes it starts over.
There can be different reasons for this behavior, I can name two of them:
- Install the firmware for your Philips DVD 6316 [1]
- Install Intel Matrix Storage Software (this one solved it in my case). [2]
I'm looking forward to hearing success stories. :-)
