| Unattend.txt Options That Are Used During an Unattended UpgradeID: Q186336 
 | 
An unattended upgrade from a previous version of Microsoft Windows NT to Microsoft Windows NT 4.0 ignores most parameters commonly set in the Unattend.txt answer file. The upgrade installation automatically reads the registry of the system being upgraded for system configuration information and uses those values during the upgrade. It is not possible to override or replace the existing system configuration information with an unattended answer file.
During an unattended upgrade, only the following parameters in the unattend
answer file are used. If NtUpgrade = yes, all other options in the answer
file, if specified, are ignored.
[Unattended]
OemPreinstall = Yes
NoWaitAfterTextMode = 1
NoWaitAfterGUIMode = 1
NtUpgrade = Yes
OverwriteOemFilesOnUpgrade = Yes
[UserData]
ProductId = "111-1111111"
[GuiUnattended]
OemSkipWelcome = 1
