How to Enable Autologon During an Automated Setup

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1
• Microsoft Windows NT Workstation versions 3.5 and 3.51
• Microsoft Windows NT Server versions 3.5 and 3.51

SUMMARY

This article describes how to enable autologon for an automated Windows NT Setup. Page 97 of the "Windows NT 3.5 Resource Kit, Volume 1" describes a method to add registry entries by modifying Txtsetup.sif. However, page 96 notes that during a fresh installation of Windows NT, the registry hives are copied in their entirety to the new registry. Only during an upgrade of Windows NT are portions of the template hives copied to the existing registry as described on page 97 in the section "Using the TXTSETUP.SIF File to Update the Registry."

MORE INFORMATION

The following entries in the registry for winlogon need to be set to enable autologon:

DefaultUserName DefaultPassword AutoAdminlogon

Unattended Setup:

The INITIAL.INF file needs to be modified as follows to set these values:

NOTE: A network or local hard disk installation is required because the INITIAL.INF file can not be modified and saved to the compact disc.

1. Expand INITIAL.IN_ to INITIAL.INF

2. Rename INITIAL.IN_ INITIAL.OR_

3. Change INITIAL.INF to read as follows:

   [Install-Win-Ini-Alter-1] ReplaceIniKeyValue "Win.ini", Winlogon, DefaultUserName, administrator ReplaceIniKeyValue "Win.ini", Winlogon, DefaultPassword, "" ReplaceIniKeyValue "Win.ini", Winlogon, AutoAdminLogon,"1"

Computer Profile Setup:

If you have not run Uplodprf.exe yet, you can modify ~Profile.inf in the CPS directory. If you have already uploaded your profile, you should modify %Systemroot\System32\Profil.inf on the distribution system.

[Install-Win-Ini-Alter] ;ReplaceIniKeyValue "Win.ini", Winlogon, DefaultUserName, $(!STF_USERNAME)

ReplaceIniKeyValue "Win.ini", Winlogon, DefaultUserName, "Administrator" ReplaceIniKeyValue "Win.ini", Winlogon, DefaultPassword, "" ReplaceIniKeyValue "Win.ini", Winlogon, AutoAdminLogon,"1"

Ifstr(i) $(!STF_PRODUCT) == "WINNT"

    ReplaceIniKeyValue "Win.ini", DeskTop,  Wallpaper, "winnt.bmp"

    ReplaceIniKeyValue "Win.ini", DeskTop,  Wallpaper, "lanmannt.bmp"
