移除按鍵組合組態

下列範例Windows PowerShell腳本會使用 Windows Management Instrumentation (WMI) 提供者來建立兩個函式，以從鍵盤篩選中移除自訂定義的按鍵組合組態。 它示範使用每個函式的數種方式。

第一個函式 Remove-Custom-Key會移除自訂按鍵組合組態。

第二個函式 Remove-Scancode會移除自訂掃描碼組態。

您無法移除鍵盤篩選的預先定義按鍵組合組態，但您可以加以停用。

    manage.  If not specified, the script will execute all WMI operations
    locally.

    [string] $ComputerName

function Remove-Custom-Key($Id) {
    <#
    .Synopsis
        Remove an instance of WEKF_CustomKey
    .Description
        Enumerate all instances of WEKF_CustomKey.  When an instance has an
        Id that matches $Id, delete it.
    .Example
        Remove-Custom-Key "Ctrl+V"

        This removes the instance of WEKF_CustomKey with a key Id of "Ctrl+V"
#>

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

    if ($customInstance) {
        $customInstance.Delete();
        "Removed Custom Filter $Id.";
    } else {
        "Custom Filter $Id does not exist.";
    }
}

function Remove-Scancode($Modifiers, [int]$Code) {
    <#
    .Synopsis
        Remove and instance of WEKF_Scancode
    .Description
        Enumerate all instances of WEKF_Scancode.  When an instance has a
        matching modifiers and code, delete it.
    .Example
        Remove-Scancode "Ctrl" 37

        This removes the instance of WEKF_Scancode with Modifiers="Ctrl" and
        Scancode=37.
#>

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

    if ($scancodeInstance) {
        $scancodeInstance.Delete();
        "Removed Scancode $Modifiers+$Code.";
    } else {
        "Scancode $Modifiers+$Code does not exist.";
    }
}

# Some example uses of the functions defined above.
Remove-Custom-Key "Ctrl+V"
Remove-Custom-Key "Numpad0"
Remove-Custom-Key "Shift+Numpad1"
Remove-Custom-Key "%"
Remove-Scancode "Ctrl" 37
