How can I modify automatic login records?

Good day @jesus garcia !

This is likely due to the architecture of the Automox agent ( currently only delivered in 32-bit ) and the architecture of the device ( which is most likely 64-bit ).

The “HKLM:\SOFTWARE” registry key is one of a handful that are virtualized in the context of 32-bit processes - this is why the properties you’re assigning don’t appear to be there when you check following the reboot!

The solution to this is to relaunch PowerShell depending on the architecture of both the process, and the device:

function Shell
{
    <#
        .SYNOPSIS

            Evaluates the executing process and system architecture to execute ScriptBlocks in the appropriate PowerShell architecture. Designed primarily for 64-bit scriptblock execution from the context of a 32-bit PowerShell instance.

        .PARAMETER Block

            [ scriptblock ] : Mandatory
                Provides the scriptblock to be executed in the evaluated shell context.

        .PARAMETER ArgList

            [ object[] ] : Optional
                Allows variable exchange between the calling process and child ( relaunched ) PowerShell process, in the event of required elevation.

        .EXAMPLE

            PS> Shell { Write-Host "Hello, world" }
            Hello, world

            PS> Shell -Block { param( $msg ); Write-Host $msg } -ArgList "Hello, world"
            Hello, world

}

Shell $configureAutoLogon

Hope this helps; let me know if you have any questions!
