O seguinte script de Windows PowerShell de exemplo utiliza os fornecedores de Windows Management Instrumentation (WMI) para o Filtro de Teclado para criar três funções para configurar o Filtro de Teclado para que o Filtro de Teclado bloqueie as combinações de teclas. Demonstra várias formas de utilizar cada função.

A primeira função, Enable-Predefine-Key, bloqueia as combinações de teclas predefinidas para o Filtro de Teclado.

A segunda função, Enable-Custom-Key, bloqueia as combinações de teclas personalizadas com os nomes das teclas em inglês.

A terceira função, Enable-Scancode, bloqueia as combinações de teclas personalizadas utilizando o código de digitalização do teclado para a tecla.

function Enable-Predefined-Key($Id) {
    <#
    .Synopsis
        Toggle on a Predefined Key keyboard filter Rule
    .Description
        Use Get-WMIObject to enumerate all WEKF_PredefinedKey instances,
        filter against key value "Id", and set that instance's "Enabled"
        property to 1/true.
    .Example
        Enable-Predefined-Key "Ctrl+Alt+Del"
        Enable CAD filtering
#>

    $predefined = Get-WMIObject -class WEKF_PredefinedKey @CommonParams |
        where {
            $_.Id -eq "$Id"
        };

    if ($predefined) {
        $predefined.Enabled = 1;
        $predefined.Put() | Out-Null;
        Write-Host Enabled $Id
    } else {
        Write-Error "$Id is not a valid predefined key"
    }
}


function Enable-Custom-Key($Id) {
    <#
    .Synopsis
        Toggle on a Custom Key keyboard filter Rule
    .Description
        Use Get-WMIObject to enumerate all WEKF_CustomKey instances,
        filter against key value "Id", and set that instance's "Enabled"
        property to 1/true.

        In the case that the Custom instance does not exist, add a new
        instance of WEKF_CustomKey using Set-WMIInstance.
    .Example
        Enable-Custom-Key "Ctrl+V"
        Enable filtering of the Ctrl + V sequence.
#>

    $custom = Get-WMIObject -class WEKF_CustomKey @CommonParams |
        where {
            $_.Id -eq "$Id"
        };

    if ($custom) {
# Rule exists.  Just enable it.
        $custom.Enabled = 1;
        $custom.Put() | Out-Null;
        "Enabled Custom Filter $Id.";

    } else {
        Set-WMIInstance `
            -class WEKF_CustomKey `

            @CommonParams | Out-Null
        "Added Custom Filter $Id.";
    }
}

function Enable-Scancode($Modifiers, [int]$Code) {
    <#
    .Synopsis
        Toggle on a Scancode keyboard filter Rule
    .Description
        Use Get-WMIObject to enumerate all WEKF_Scancode instances,
        filter against key values of "Modifiers" and "Scancode", and set
        that instance's "Enabled" property to 1/true.

        In the case that the Scancode instance does not exist, add a new
        instance of WEKF_Scancode using Set-WMIInstance.
    .Example
        Enable-Scancode "Ctrl" 37
        Enable filtering of the Ctrl + keyboard scancode 37 (base-10)
        sequence.
#>

    $scancode =
        Get-WMIObject -class WEKF_Scancode @CommonParams |
            where {
                ($_.Modifiers -eq $Modifiers) -and ($_.Scancode -eq $Code)
            }

    if($scancode) {
        $scancode.Enabled = 1
        $scancode.Put() | Out-Null
        "Enabled Custom Scancode {0}+{1:X4}" -f $Modifiers, $Code
    } else {
        Set-WMIInstance `

            -argument @{Modifiers="$Modifiers"; Scancode=$Code} `
            @CommonParams | Out-Null

        "Added Custom Scancode {0}+{1:X4}" -f $Modifiers, $Code

Enable-Custom-Key "Ctrl+V"
Enable-Custom-Key "Numpad0"
Enable-Custom-Key "Shift+Numpad1"
