*A. Unattended Install - UserName = YourName
in winnt.sif file - unattendswitch="Yes" - UserName is used Automatically
useraccounts.cmd with UserName is created in *OEM* Folder copied to USB-drive
(Selecting Unattended Install in the Editor instead of Cancel will enable you to skip the Welcome Screens by filling in the information right now.)
*B. Semi-Unattended Install - UserName = None
in winnt.sif file - unattendswitch="No" - UserNames are given Manually at Windows Welcome Screens
useraccounts.cmd is Renamed to Inactive txt file in *OEM* Folder copied to USB-drive
*C. Cancel - In all cases Selecting Cancel keeps given Settings for winnt.sif file and *OEM* folder Unchanged
If you'd just rather fill in the information during the actual install of WinXP on your PC it's the same exact thing as choosing Unattended Install, Unattended Install just allows you to fill in the information now instead of later.
