Adición de combinaciones de teclas bloqueadas
En el ejemplo siguiente Windows PowerShell script se usan los proveedores de Instrumental de administración de Windows (WMI) para el filtro de teclado para crear tres funciones para configurar el filtro de teclado para que el filtro de teclado bloquee las combinaciones de teclas. Muestra varias maneras de usar cada función.
La primera función, Enable-Predefine-Key, bloquea las combinaciones de teclas predefinidas para El filtro de teclado.
La segunda función, Enable-Custom-Key, bloquea las combinaciones de teclas personalizadas mediante los nombres de clave en inglés.
La tercera función, Enable-Scancode, bloquea las combinaciones de teclas personalizadas mediante el código de examen del teclado para la tecla.

.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

Write-Host Enabled $Id
} else {

<#
.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.Put() | Out-Null;
"Enabled Custom Filter $Id.";
} else {
Set-WMIInstance `
-class WEKF_CustomKey `
-argument @{Id="$Id"} `
@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, $Code
} else {
Set-WMIInstance `
-class WEKF_Scancode `
-argument @{Modifiers="$Modifiers"; Scancode=$Code} `
@CommonParams | Out-Null
"Added Custom Scancode {0}+{1:X4}" -f $Modifiers, $Code
