I just found out about nlite, and I think it is great, but I have a few questions.

1. Can I use nLite to make isos with the serial already in them so I don't have to enter it? Pre Enter

2. Can I customize an iso?

Thanks for the help.

1. Yes

2. Customize how?

I have Windows XP Service Pack 2, but it is in iso format. It has a serial key. Can I use nLite to add the serial to the iso?

Excuse anonymous_user for not being clear enough, in fact he meant "yes".
Maybe you need an explanation on what an iso is.... its a compressed file that contains a cdrom image. All the files can be extracted or burned to a cdrom.

1. Yes, you can add your key so the installation will automate it.

2. No, nLite will not edit an ISO, but you can use PowerISO/UltraISO to edit the ISO. This is why you make all the last minute changes to the source files before you click on the "Create ISO" button in nLite.
