Hi Nuhi ! I dont know what soft i have installed that make games not working. I disabled few services like "Windows defender, Security Center, Offline Files, Windows Updates, Windows Search). But i must say that i love to use every time the vLite option you made "Remove Winsxs". Maybe removing winsxs make conflict with my config at this point. I must identify the culprit after doing some test again ! But for now i wait the final version of Vista SP1 ! Thanks for your response !
