http://unattended.msfn.org/global/examples.htm If you scroll down to where it shows the product key (this is under [userdata]), you'll see that it is all X's. I know thats just an example, but since this is a batch response file type and the ISO responds off the coding in those files, is it possible for me to use that key? And if this is possible, what happenes if I use a serial key that does come with Windows, will it respond with it or also take the serial key with it.
