Me, I use first Gimagex then Vlite and I finally rt7lite if we use first rt7lite is an error message launching Vlite about the boot (boot-optimized by rt7lite and not "compatible" with vLite) bapt I do not really understand what you meant with the bolded part. As recommended, I used Gimagex to create a modified wim of Windows 7 SP1 (MSDN). Subsequently, I used RT 7 Lite to integrate Windows updates and remove components. However, after this step, if I use vLite to slim down this image, vLite will stop responding. Is this what you meant by error message launching vLite? You suggested to use vLite after using GImagex, but vLite cannot be used to integrate Windows updates to the image. Moreover, we should not remove components prior to integrating updates to the image. By your method "I use first Gimagex then Vlite and I finally rt7lite", could you explain when the time to integrate updates is? It would be very helpful if you can share your RT 7 Lite and vLite preset, so that I would know components that should be removed by respective software. Thank you very much. answered to your MP My RT 7 Lite and vLite preset Vlite.ini RT 7lite.inf
