Como usar os scripts do PowerShell com o provedor de ponte WMI

Aplica-se a: ✅ Windows 11, ✅ Windows 10

Este artigo aborda o uso de scripts de cmdlet do PowerShell para definir configurações de política por usuário e por dispositivo e como invocar métodos por meio do provedor de ponte WMI.

Definindo configurações de política por dispositivo

Esta seção fornece um script de exemplo de cmdlet do PowerShell para definir as configurações por dispositivo por meio do Provedor de Ponte WMI. Se uma classe der suporte a configurações de dispositivo, deverá haver um qualificador de nível de classe definido para InPartition("local-system").

Para todas as configurações de dispositivo, o cliente da Ponte WMI deve ser executado em usuário do sistema local. Para fazer isso, baixe a ferramenta https://technet.microsoft.com/sysinternals/bb897553.aspx psexec e execute psexec.exe -i -s cmd.exe a partir de um prompt de comando de administrador com privilégios elevados.

O exemplo de script nesta seção usa a classe MDM_Policy_Config01_WiFi02:

[dynamic, provider("DMWmiBridgeProv"), InPartition("local-system")]
class MDM_Policy_Config01_WiFi02
{
  string InstanceID;
  string ParentID;
  sint32 AllowInternetSharing;
  sint32 AllowAutoConnectToWiFiSenseHotspots;
  sint32 WLANScanMode;
};

O script a seguir descreve como criar, enumerar, consultar, modificar e excluir instâncias.

$namespaceName = "root\cimv2\mdm\dmmap"
$className = "MDM_Policy_Config01_WiFi02"

# Create a new instance for MDM_Policy_Config01_WiFi02
New-CimInstance -Namespace $namespaceName -ClassName $className -Property @{ParentID="./Vendor/MSFT/Policy/Config";InstanceID="WiFi";AllowInternetSharing=1;AllowAutoConnectToWiFiSenseHotspots=0;WLANScanMode=100}

# Enumerate all instances available for MDM_Policy_Config01_WiFi02
Get-CimInstance -Namespace $namespaceName -ClassName $className

# Query instances with matching properties
Get-CimInstance -Namespace $namespaceName -ClassName $className -Filter "ParentID='./Vendor/MSFT/Policy/Config' and InstanceID='WiFi'"

# Modify existing instance
$obj = Get-CimInstance -Namespace $namespaceName -ClassName $className -Filter "ParentID='./Vendor/MSFT/Policy/Config' and InstanceID='WiFi'"
$obj.WLANScanMode=500
Set-CimInstance -CimInstance $obj

# Delete existing instance
try
{
    $obj = Get-CimInstance -Namespace $namespaceName -ClassName $className -Filter "ParentID='./Vendor/MSFT/Policy/Config' and InstanceID='WiFi'"
    Remove-CimInstance -CimInstance $obj
}
catch [Exception]
{
    write-host $_ | out-string
}

Definindo configurações por usuário

Esta seção fornece um script de exemplo de cmdlet do PowerShell para definir as configurações por usuário por meio da ponte WMI. Se uma classe der suporte às configurações do usuário, deverá haver um qualificador de nível de classe definido para InPartition("local-user").

O exemplo de script nesta seção usa a classe MDM_Policy_User_Config01_Authentication02:

[dynamic, provider("DMWmiBridgeProv"), InPartition("local-user")]
class MDM_Policy_User_Config01_Authentication02
{
  string InstanceID;
  string ParentID;
  sint32 AllowEAPCertSSO;
};

Observação

Se o usuário conectado no momento estiver tentando acessar ou modificar as configurações do usuário por conta própria, é mais fácil usar o script de configurações por dispositivo da seção anterior. Todos os cmdlets do PowerShell devem ser executados em um prompt de comando de administrador com privilégios elevados.

Se estiver acessando ou modificando configurações para um usuário diferente, o script do PowerShell será mais complicado porque a ponte WMI espera que o SID do usuário seja definido no Contexto Personalizado MI, que não tem suporte em cmdlets nativos do PowerShell.

Observação

Todos os comandos devem ser executados no sistema local.

O comando wmic useraccount get name, sid do Windows pode ser usado para obter o SID do usuário. O exemplo de script a seguir pressupõe que o SID do usuário seja S-1-5-21-4017247134-4237859428-3008104844-1001.

$namespaceName = "root\cimv2\mdm\dmmap"
$className = "MDM_Policy_User_Config01_Authentication02"

# Configure CIM operation options with target user info
$options = New-Object Microsoft.Management.Infrastructure.Options.CimOperationOptions
$options.SetCustomOption("PolicyPlatformContext_PrincipalContext_Type", "PolicyPlatform_UserContext", $false)
$options.SetCustomOption("PolicyPlatformContext_PrincipalContext_Id", "S-1-5-21-4017247134-4237859428-3008104844-1001", $false)

Invocando métodos

Esta seção fornece um script de exemplo de cmdlet do PowerShell para invocar um método de objeto de ponte WMI. O script a seguir deve ser executado no usuário do sistema local. Para fazer isso, baixe a ferramenta https://technet.microsoft.com/sysinternals/bb897553.aspx psexec e execute psexec.exe -i -s cmd.exe a partir de um prompt de comando de administrador com privilégios elevados.

O exemplo de script nesta seção usa o método UpgradeEditionWithProductKeyMethod da classe MDM_WindowsLicensing .

$namespaceName = "root\cimv2\mdm\dmmap"
$className = "MDM_WindowsLicensing"
$methodName = "UpgradeEditionWithProductKeyMethod"
$fakeProductKey = "7f1a3659-3fa7-4c70-93ce-0d354e8e158e"

$session = New-CimSession

$params = New-Object Microsoft.Management.Infrastructure.CimMethodParametersCollection
$param = [Microsoft.Management.Infrastructure.CimMethodParameter]::Create("param", $fakeProductKey, "String", "In")
$params.Add($param)

try
{
    $instance = Get-CimInstance -Namespace $namespaceName -ClassName $className -Filter "ParentID='./Vendor/MSFT' and InstanceID='WindowsLicensing'"
    $session.InvokeMethod($namespaceName, $instance, $methodName, $params)
}
catch [Exception]
{
    write-host $_ | out-string
}
