Ok, my friend has made an unattended Cd with his stuff, now is it possible for me to edit it and add stuff/remove stuff to it?

For Example if he has Vmware unattended i want to remove that, how would i go about, this is an ISO, dvd. I also want to add my own (documents + a few more window updates) I also want to change the serial number.

I would not recomend using your friends as a base but a guid e only. Much better to use all your own files & follow the guide its a lot cleaner to do it that way. Everything you mentioned is achievable if you follow the relevant guides here & members postings using the Search Button. Good luck.

Start my dumping the cd to your HDD, then start editing everything . It's as simply as that.
