wow, i followed your guide with a little modifications and my partition c only takes less than 1.8GB (without virtual memory), it's so cool, thanks for your efforts. but i got some questions: 1.) REM Image Index (pre-vLite: 1 HomeStarter, 2 Home Premium, 3 Professional, 4 Ultimate) actually, i found there are 5 indexes in rtm install.wim. Ultimate index is 5 not 4, you may check my attched log. 2.)why do we need repeat steps 15 and 16 in your guide? 3.)in your guide, you said: "Now the final step is a vLite dummy run. vLite the image and apply one tweak", what does this mean? shall i run vlite then rebuild? 4.)removal32.bat removes a lot of packages. how to get a full package list together with description so that i can create my customization system depend on my requirement. wim.txt
