다음 샘플 Windows PowerShell 스크립트는 키보드 필터용 WMI(Windows Management Instrumentation) 공급자를 사용하여 키보드 필터가 키 조합을 차단하도록 키보드 필터를 구성하는 세 가지 함수를 만듭니다. 각 함수를 사용하는 여러 가지 방법을 보여 줍니다.
첫 번째 함수인 Enable-Predefine-Key는 키보드 필터에 대해 미리 정의된 키 조합을 차단합니다.
두 번째 함수인 Enable-Custom-Key는 영어 키 이름을 사용하여 사용자 지정 키 조합을 차단합니다.
세 번째 함수인 Enable-Scancode는 키에 대한 키보드 검사 코드를 사용하여 사용자 지정 키 조합을 차단합니다.

.Synopsis
This script shows how to use the built in WMI providers to enable and add
keyboard filter rules through Windows PowerShell on the local computer.
.Parameter ComputerName
Optional parameter to specify a remote machine that this script should
manage. If not specified, the script will execute all WMI operations
locally.

.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

.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.

$_.Id -eq "$Id"

<#
.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)
}
