您可以使用以下命令进行设置：
rundll32.exe %SystemRoot%\system32\shell32.dll,Control_RunDLL %SystemRoot%\system32\desk.cpl desk,@Themes /Action:OpenTheme /file:"C:\Windows\Resources\Themes\aero.theme"
需要注意的是，这将显示主题选择对话框。您可以直接关闭该对话框。
想通过编程方式更改当前主题当然有很好的理由，例如自动化测试工具可能需要在各种主题之间切换以确保应用程序与所有主题都能正常工作。
作为用户，您可以通过在Windows Explorer中双击.theme文件，然后关闭弹出的控制面板小程序来更改主题。您也可以轻松地从代码中实现相同的功能。以下步骤适用于我，但我只在Windows 7上进行了测试。
SHGetKnownFolderPath()获取用户的“本地应用数据”文件夹。主题文件存储在Microsoft\Windows\Themes子文件夹中。存储在该文件夹中的主题文件直接应用，而存储在其他位置的主题文件则在执行时被复制。因此最好仅使用该文件夹中的文件。ShellExecute()执行在步骤1中找到的.theme文件。FindWindow('CabinetWClass', 'Personalization')来获取在应用主题时弹出的控制面板窗口的句柄。在非美国英语版本的Windows上，“个性化”标题可能会有所不同。PostMessage(HWND, WM_CLOSE, 0, 0) 来关闭控制面板窗口。这并不是一个非常优雅的解决方案，但它可以完成工作。
％LocalAppData％\Microsoft\Windows\Themes。有一个％AppData％\Microsoft\Windows\Themes，但里面没有主题文件。 - XP1.themepack。下载或手动自定义主题，右键单击并选择“保存主题以共享”为 .themepack 文件。这可以被“运行”，并更改当前主题。 - Nigel Touch我知道这是一个旧的工单，但今天有人问我如何做到这一点。所以从Mike上面的帖子开始，我整理了一下内容，添加了注释，并发布了完整的C#控制台应用程序代码：

</code>我不确定这是否是新功能，但你可以双击.theme文件，然后Windows 10会应用该主题。因此，你可以轻松使用PowerShell执行以下操作：
$Windows10Theme = "C:\Windows\Resources\Themes\aero.theme"
Invoke-Expression $Windows10Theme
我一直在尝试通过命令行更改Windows主题，发现通过执行主题文件可以被Windows 10应用。因此，在您的批处理文件中，您可以使用以下其中一行：
C:\Users\%USERNAME%\AppData\Local\Microsoft\Windows\Themes\Dark_Mode.theme
或者
C:\Users\%USERNAME%\AppData\Local\Microsoft\Windows\Themes\Light_Mode.theme
taskkill /F /IM systemsettings.exe
@echo off
if %1 == dark (
REM ================== Go Dark ==================
color 09
echo.
echo Applying DARK MODE
echo Windows Theme ...
C:\Users\%USERNAME%\AppData\Local\Microsoft\Windows\Themes\Dark_Mode.theme
timeout /T 1 /nobreak > nul
taskkill /F /IM systemsettings.exe > nul
echo DONE
) else (
REM ============== Return to Light ==============
color 30
echo.
echo Applying LIGHT MODE
echo Windows Theme ...
C:\Users\%USERNAME%\AppData\Local\Microsoft\Windows\Themes\Light_Mode.theme
timeout /T 1 /nobreak > nul
taskkill /F /IM systemsettings.exe > nul
echo DONE
)
REM ================== Goodbye ==================
echo.
echo Goodbye
cls
exit
dark或任何其他string。然后，您可以准备两个快捷方式到该批处理文件，每个快捷方式在其属性的“快捷方式”选项卡中的“目标”框中都有以下内容之一：C:\full-path-to-your-batch-file\theme.bat dark
或者
C:\full-path-to-your-batch-file\theme.bat light
较新的Windows版本（Windows 8和8.1，尚未在W10上尝试）的命令为：
rundll32.exe themecpl.dll,OpenThemeAction %1
C:\WINDOWS\system32\rundll32.exe C:\WINDOWS\system32\themecpl.dll,OpenThemeAction %LocalAppData%\Microsoft\Windows\Themes\yourtheme.theme
基本上，这是从注册表中提取的与.theme和.themepack扩展名相关的个性化CPL“打开”命令...
使用此命令后，您仍将获得打开的个性化窗口，因此要在程序中关闭它，您必须使用上面提到的建议方法之一...（我个人更喜欢Powershell脚本）
我认为最好的方法是打开目标的.msstyles文件（在c:\windows\resources\themes中），这将弹出显示属性框。此时，您可以使用窗口子类化程序来编程式地单击正确的按钮。
我刚刚意识到，你可以双击主题，它就会自动切换 - 这样更简单，所以只需执行主题即可，例如批处理文件：
:: Reactivate my theme after an remote desktop session
:: We must select another theme first before we can select ours again and hence re-activate Aero, please wait..."
@echo Off
"C:\Windows\Resources\Themes\aero.theme"
::echo "Simulating a pause while"
ping 127.0.0.1 -n 10 > null && "D:\Users\danielsokolowski\Windows 7 Aero Themes\`danielsokolowski` Theme (without Glass).theme"
::or ping 127.0.0.1 -n 3 > null && "%userprofile%\AppData\Local\Microsoft\Windows\Themes\`danielsokolowski` Theme (without Glass).theme"

针对Windows 10，我使用PowerShell编写了这个简单的解决方案（也可用于DSC）。
# Apply your theme
& "C:\Windows\Resources\Themes\Brand.theme"
# We need to wait for the theme to be applied
Start-Sleep -s 5
# Close the settings window that is opened by the action above
$window = Get-Process | Where-Object {$_.Name -eq "SystemSettings"}
Stop-Process -Id $window.Id
