使用 Python 更改注册表值时如何处理 PermissionError

如何解决使用 Python 更改注册表值时如何处理 PermissionError

我正在尝试在 python 中编写一个程序，如果它处于亮模式，则将 Windows 计算机更改为暗模式，反之亦然。但是，当我运行代码时，我得到一个响应：“PermissionError: [WinError 5] Access is denied。”谁能帮我？此外，这是我第一次使用注册表，所以我意识到这段代码可能非常低效。

import winreg
# goes to correct directory in registry
with winreg.ConnectRegistry(None,winreg.HKEY_CURRENT_USER) as hkey:
    with winreg.OpenKey(hkey,"SOFTWARE") as hkey2:
        with winreg.OpenKey(hkey2,"Microsoft") as hkey3:
            with winreg.OpenKey(hkey3,"Windows") as hkey4:
                with winreg.OpenKey(hkey4,"CurrentVersion") as hkey5:
                    with winreg.OpenKey(hkey5,"Themes") as hkey6:
                        with winreg.OpenKey(hkey6,"Personalize") as hkey7:
                            # checks if windows is using dark or light mode
                            answer = winreg.QueryValueEx(hkey7,"AppsUseLightTheme")
                            value = answer[0]
                            if value == 0:
                                insert = 1
                            elif value == 1:
                                insert = 0
                            # sets windows to dark or light mode,opposite of what it was before
                            winreg.SetValueEx(hkey7,"AppsUseLightTheme",4,insert)
                            print(value)
                            print(insert)
                            input()

解决方法

如文档所述，winreg.OpenKey 默认为 access=KEY_READ。作为旁注，您可以一次性完成所有这些子项：

    with winreg.OpenKey(hKey,"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Themes\\Personalize",access=winreg.KEY_READ|winreg.KEY_WRITE) as hkey2:
