Hi, I am new to Sysprep, but I into this situation as well.  I hope you can assist me of when I should run the sysprep -generalize?  Do I prepare the sysprep.inf first?  Do I have to enter product key in the sysprep.inf too?  Once the sysprep.inf is done, should I start sysprep -generalize command? Also, can I run this command options with sysprep -generalize,  cd to c:\sysprep execute the command line "sysprep -reseal -mini -generalize -quiet"  without the quotes. Greatly appreciate for all the help!
