Does Automox Use x86 powershell?

Sure does. There is a way to execute 64-bit PowerShell. To do that, checkout https://support.automox.com/help/enforce-windows-registry-settings-worklet just under the “64-Bit Registry Workaround” section or see the 64-bit example below.

Before that, the net commands still work for x86 powershell

net user ITAdmin $password /ADD /Y

net localgroup Administrators ITAdmin /ADD

Here is a 64-bit example

$scriptblock = {

    ############# EDIT HERE ############
    $account = "ITAdmin"
    $description = "IT local admin account"

        if ($ConvertToSecureString.IsPresent) {

        } else {

        }
    }

    # Generate random password
