Aero theme problem

[wnied]

When I right click my desktop, and choose personalize, I then click themes and I do not see Windows Aero theme... I wish to change to this theme because I want to try out Windows Dream Scene, and it tells me that to run Windows Dream Scene, I need to use Aero theme. I have Windows Vista Ultimate with all the updates and extras available for it, yet Aero theme doesnt show up under themes....

Can anyone help here?
Thanks in advance.

Instead of Themes go to "Window Color and Appearance" then "Open classic appearance properties for more color options". Windows Aero should show up in the list of color schemes.
