The Intel GMA 900 is a very old and low-end integrated graphics. As per Intel the onboard graphic memory is not capable of meeting minimum requirements Aero Glass. And also there is no upcoming WDDM drivers available for the same. But I had seen the old drivers that worked really well on Windows Vista and Windows 7. I am trying to turn on the same on my existing system but it fails. I had seen my friend who has a Vista system and he able to use Aero Glass on it with the same Intel GMA 900 onboard video memory. My doubt is about the RTM version of Windows 7. In which I want to know that will I be able to use Aero Glass on the pc that has GMA 900. Also what driver version will I have to use.
