Windows 10 Nachtmodus über cmd starten?

Kann man den Nachtmodus über cmd starten?

Answer 1

Mach es doch mit Powershell (als Admin):

New-ItemProperty -Path HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize -Name AppsUseLightTheme -Value 0 -Type Dword -Force

Dies erstellt eine neues Registery Dword "AppUseLightTheme" und setzt den Wert auf "0".

Wenn du es wirklich in cmd brauchst kann ich dir sicher etwas basteln :)

Ich hab da mal was genutzt, das auch funktionierte. Habs aber jetzt schon eine Weile nicht mehr ausprobiert. 

[cmdletbinding(SupportsShouldProcess=$true)]
    param(
        [Parameter(
            Mandatory=$true,
            ParameterSetName='BlueShift Off'
        )]
        [switch] $DisableBlueLight,
        [Parameter(
            Mandatory=$true,
            ParameterSetName='BlueShift On'
        )]
        [switch] $EnableBlueLight,
                [Parameter(
            Mandatory=$true,
            ParameterSetName='Automatic Off'
        )]
        [switch] $DisableAutomaticSchedule,
        [Parameter(
            Mandatory=$true,
            ParameterSetName='Automatic On'
        )]
        [switch] $EnableAutomaticSchedule,
        [Parameter(
            Mandatory=$false,
            ParameterSetName='BlueShift On'
        )]
        [Parameter(
            Mandatory=$false,
            ParameterSetName='BlueShift Off'
