Aggiungere combinazioni di tasti bloccate

• Si applica a:

  ✅ Windows 11, ✅ Windows 10

L'esempio seguente Windows PowerShell script usa i provider di Strumentazione gestione Windows (WMI) per il filtro da tastiera per creare tre funzioni per configurare il filtro da tastiera in modo da bloccare le combinazioni di tasti. Illustra diversi modi per usare ogni funzione.

La prima funzione, Enable-Predefine-Key, blocca le combinazioni di tasti predefinite per Il filtro da tastiera.

La seconda funzione, Enable-Custom-Key, blocca le combinazioni di chiavi personalizzate usando i nomi delle chiavi inglesi.

La terza funzione, Enable-Scancode, blocca le combinazioni di tasti personalizzate usando il codice di analisi della tastiera per la chiave.

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"

        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"

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.
