Terraform script Windows Module set account lockout policy & minimum password length Azure

Question

I am working on a Azure Terraform script, recently installed windows module when windows bootup there is no Account Lockout Policy & Minimum Password Length Policy set by default, is there any way I can define in terraform script in windows module. Thanks.

resource "azurerm_virtual_machine_extension" "vm" {
  name                 = var.vm_hostname
  count                = (var.is_windows_image || contains(list(var.vm_os_simple, var.vm_os_offer), "WindowsServer")) ? var.nb_instances : 0
  virtual_machine_id   = azurerm_virtual_machine.vm-windows[count.index].id
  publisher            = "Microsoft.Azure.Extensions"
  type                 = "CustomScript"
  type_handler_version = "2.0"

   settings = <<SETTINGS
    {
      "commandToExecute": "net accounts /minpwlen:8 && net accounts /maxpwage:45 && net accounts /minpwage:0 && net accounts /lockoutduration:30 && net accounts /lockoutthreshold:3 "    
      }
 SETTINGS

  
}

and I am getting error.

resource "azurerm_virtual_machine_extension" "vm" {
  name                 = "${var.vm_hostname}-${count.index}"
  count                = (var.is_windows_image || contains(list(var.vm_os_simple, var.vm_os_offer), "WindowsServer")) ? var.nb_instances : 0
  virtual_machine_id   = azurerm_virtual_machine.vm-windows[count.index].id
  publisher            = "Microsoft.Compute"
  type                 = "CustomScriptExtension"
  type_handler_version = "1.9"

   settings = <<SETTINGS
    {
      "commandToExecute": "powershell -ExecutionPolicy Unrestricted -Command net accounts /minpwlen:8 && net accounts /maxpwage:45 && net accounts /minpwage:0 && net accounts /lockoutduration:30 && net accounts /lockoutthreshold:3 "    
      }
 SETTINGS

  
}

here is the piece of code which resolved my issue, this mistake i have been doing is using wrong extension which was for the Linux correct extension and code is pasted here.

If you want to configure the Windows VM in the creation time, you can use the cloud-init with the PowerShell script. In terraform, you can use the custom_data. And if you do not care when to configure, you can use the VM extension to do the things you want after creating the VM with resource azurerm_virtual_machine_extension.
