In unattended mode there are 5 options -provide defaults -fully automated -hide pages -read only -gui attended -prompt repair What I intend to do is enter all the values as default, but may change the values based on the current condition of my computer. So I chose provide defaults, but when I installed with this version, the windows does not show all the dialog pages. It didn't show any serial key page so I do not have the option to enter another key if I want to change it. Is this an error or this mode is designed like this? If so, is there any mode I can enter the serial key as default and give the user the ability to enter their own key on install? Also, what does wmp.dll and t2embed.dll do? The blue screen setup warned me of the missing files, I know I removed some components using nlite, but they do not tell me what files are removed by removing that component.
