Ok, I'm very new to this. and in the 2 days I've been tinkering with making an unattended XP disk, I've got it working installing XP with most of the updates using nLite, and Office 2003 with all the critical updates. Now I'm trying to add applications using a .cmd batch file. One of the apps is PLUS! Media edition which requires a product key. How would I automate the product key process so that the install is fully automated?

yuo can install plus with the /qb switch as for the serial it must be stored in the registry, use a tool like regshot before and then after entering the serial number

How would I add it to the registry? In the guide, I saw a section for reg tweaks, but it says its not finished yet.
