So, I saw DX11 is out for Vista sp2. I checked for available updates, and nothing there. I refreshed the available updates, and still nothing there. So I went to make sure that I had the full version of sp2 installed, and found out I still have the RC version. v.286 Is there an easy way to upgrade to the final sp2? I have a feeling the RC version is the reason I can't upgrade to DX11.
