I recently made an unattended setup CD with the latest SP2, updates, drivers, and everything like that when I last set up my PC in April. I even created up a WINNT.sif file which included my XP CD key and username, etc- so that the setup would be completely unattended.  I want to burn a new XP Setup CD for my dad- but want to remove my XP CD-key and name from the CD so he can use his. I want to leave it blank too so that he will be able to use the same CD with all theh updates, etc. already installed on multiple machines.  Is this merely a matter of erasing the CD-key from the WINNT.sif file? I copied all the contents of my XP Setup CD to my hard drive and edited the WINNT.sif file for a friend, so I know how to create a new bootable image and burn the iso and everything... but when I did it for my friend he put his own CD key and username into the .sif file. What I want to do now is make it completely blank.  Could someone let me know if this would work? Just erasing those certain entries in the winnt.sif file? Here is a copy of my winnt.sif file (personal info removed of course)... just want to make sure it works!  ---------------------------------------------------------  ;  ; Generated by nLite 0.99.9 beta  ;  [Data]  Autopartition = 0  MsDosInitiated = 0  UnattendedInstall = Yes  [unattended]  UnattendMode = FullUnattended  UnattendSwitch = Yes  OemPreinstall = Yes  OemSkipEula = Yes  FileSystem = *  WaitForReboot = No  NoWaitAfterTextMode = 1  NoWaitAfterGUIMode = 1  TargetPath = Windows  Hibernation = No  [Display]  Xresolution = 1024  Yresolution = 768  BitsPerPel = 32  Vrefresh = 75  [systemRestore]  MaximumDataStorePercentOfDisk = 10  [GuiUnattended]  AutoLogon = Yes  AdminPassword = *  TimeZone = 04  OEMSkipRegional = 1  OemSkipWelcome = 1  [shell]  DefaultThemesOff = Yes  DefaultStartPanelOff = Yes  [Components]  [userData]  ProductKey = "XXXXXXXXXXXXXXXXXXX" <--Can I just make these fields empty or have a * in them?
