Hi, First, sorry for my bad english.

I manage MDT for deployment on non-domain computer wich be used by public user I have two accounts on these computer "Public" with no password and "Admin" with password

I want to set the "Public" profil by default when (re)starting the computer, so if log with Admin and stop the computer, the next user who turn it on have the "Public" profil instead of my last logged on Admin account

I try add these registry key via Powershell and Bat script in so many way : reg add, reg import regedit /s etc..
Set-ItemProperty -Path $registryPath -Name "DefaultUserName" -Value "EPN" -Type String
Set-ItemProperty -Path $registryPath -Name "DefaultPassword" -Value "" -Type String
Set-ItemProperty -Path $registryPath -Name "AutoAdminLogon" -Value "1" -Type String

I also try to make an application an run it into the tasksequence but still the same problem

When i run the commande localy : Everything working great

When i run a Task Sequence calling the Script : Only two value are created but in a wrong way :

DefaultUserName is created but blank

DefaultPassword is unexistant

AutoAdminLogon is created but with "0" value in

I don't understand why locally it's works like a charm but with MDT the reg are not created as i want

    Hi,

    Please use this method to test your installations before deploying them with MDT Deploy. It’s the perfect way to ensure consistency and troubleshoot any issues.

    To become the LOCAL SYSTEM account and test application deployment, you can use PsExec. Here’s how:

    Run PsExec: In the Command Prompt, enter the following command:

    PsExec.exe -s -i cmd.exe

    User's image User's image

    User's image

    $registryPath = '"HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon"'
 
$command = 'reg add ' + $registryPath + ' /v DefaultPassword /t REG_SZ /f'
 
invoke-expression $command
 
$command = 'reg add ' + $registryPath + ' /v DefaultUserName /t REG_SZ /d "EPN" /f'
 
invoke-expression $command
 
$command = 'reg add ' + $registryPath + ' /v AutoAdminLogon /t REG_SZ /d "1" /f'
 
invoke-expression $command
