I don get the new Windows Vista AERO Glass user interface, why?
Windows AERO Glass requires that you have a minimum of 64 MBs video RAM that is Direct X 9 compliant and supports the Windows Display Driver Model (WDDM). If your video card does not meet these requirements, its the likely cause why you are not seeing it. For onboard/integrated cards, you need to have 1 GB of dual channel memory installed with 512 MBs of RAM allocated to the system. The amount of Video RAM also determines the resolution size your Display can use.
