如何使用 Powershell 将注册表值获取到变量？（在 Windows 10 中实现以编程方式切换暗模式）

我正在为 Windows 10 实现暗黑模式切换器。我发现那可以通过以下方式启用暗模式

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

和灯光模式

Set-ItemProperty -Path HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize -Name AppsUseLightTheme -Value 1 -Type Dword -Force

现在我想实现切换。我试过了

Get-ItemProperty -Path HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize -Name AppsUseLightTheme

并没有得到 0 或 1，而是得到了如下输出：

AppsUseLightTheme : 1
PSPath            : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize
PSParentPath      : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes
PSChildName       : Personalize
PSDrive           : HKCU
PSProvider        : Microsoft.PowerShell.Core\Registry

我实际上如何将1其保存在变量中并进行切换？

答案1

好的，它实际上很简单，必须使用点符号来获取字段值：

$mode = (Get-ItemProperty -Path HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize -Name AppsUseLightTheme).AppsUseLightTheme
$newMode = 1 - $mode
Set-ItemProperty -Path HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize -Name AppsUseLightTheme -Value $newMode -Type Dword -Force

下面是一个 AutoHotKey 脚本，用于打开Win+暗模式Q：

psScript =

  $mode = (Get-ItemProperty -Path HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize -Name AppsUseLightTheme).AppsUseLightTheme
  $newMode = 1 - $mode
  Set-ItemProperty -Path HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize -Name AppsUseLightTheme -Value $newMode -Type Dword -Force
)

#NoEnv  ; Recommended for performance and compatibility with future AutoHotkey releases.
