Help with System Preparation Tool 2.0

just running the sysprep tool and it gives me the menu for the system preparation tool 2.0 and would like some help on the options available please. I have searched the net but too no luck.
Basically I can click either factory or reseal.
What i have done is setup a PC with standard applications and customised. I now what the sysprep tool to reset the SID and once shutdown i will ghost the image onto CD so can deploy on similar PC’s.
Cheers for any help
