Question on SetupComplete.cmd

HI

1) What are the commands that I put in SetupComplete.cmd script to
delete all data and files created during an automated installation of
Vista?

2) In SetupComplete.cmd file, I have to include a decision-making
structure (such as IF or CASE), which permits to take certain actions
depending on the license key entered at the installation of Vista
Ultimate SP1 64-bit Retail?


3) After executing the instructions contained in SetupComplete.cmd
file, I have to enter a command that reboots the computer completely
before a user can make his first Login after the installation of Vista
Ultimate SP1 64-bit Retail. So, what is the command able to run it in
properly?

THANKS

BYE
