INFO: Unattend.txt Options That Are Used During an Unattended Upgrade

ID: Q186336

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Workstation version 4.0

SUMMARY

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.

MORE INFORMATION

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

NOTE: During an upgrade installation, if OemPreinstall is set to yes, the $OEM$ directory structure is copied to the local hard drive, but the directory structure is not used during the installation. Any options specified in a Cmdlines.txt file are ignored. Windows NT Setup will recognize and use the $OEM$ directory structure only if NtUpgrade is set to No in the Unattend.txt answer file. Most options commonly applied with a Cmdlines.txt file can still be applied during the unattended upgrade by specifying the winnt/winnt32 command line switch /E. The /E switch allows setup to run an external program at the end of GUI-mode setup. This option can be used to apply a service pack or to launch other custom applications during setup. For additional information on the /E command line switch, please see Chapter 5 of the Windows NT Deployment Guide.
