Nick White published a screenshot of the new Windows Standard Theme in Windows Vista
Windows Vista uses the Windows Display Driver Model (WDDM) to deliver some amazing user experience features collectively called Windows Aero which include; Desktop Composition, Glass window frames with colored glass, window thumbnails and Flip3D, a new window management facility. All of the Windows Aero features are enabled in Windows Home Premium, our Business SKUs, and Ultimate assuming you have the appropriate hardware. On Home Basic, you get Desktop Composition with opaque colored glass windows frames.New Windows Standard Theme in Windows Vista
If you don’t have a display driver capable of running WDDM you’ll get the Windows Vista Basic theme which does not benefit from some of the more graphically intensive features such as desktop composition and glass window frames. This is a good, clean interface called the Basic or Standard theme, but lacking the glass window frames of Aero.
