您可能需要更改与某些协议^(protocols)和文件扩展名^{(file extensions)}关联的默认程序。我们大多数人最终将默认的照片查看器^{(Photo Viewer)}、浏览器等更改为我们选择的另一个程序。如果您是其中之一，那么这篇文章将向您展示如何更改Windows 11/10 中的默认照片查看器。^{(Photo Viewer)}

^(Change)在Windows 11/10更改默认照片查看器^{(Photo Viewer)}

Windows 11/10中有两种方法可以设置或更改默认程序。一种是经典的控制面板^{(Control Panel)}方法，另一种更简单——通过新的设置^(Settings)应用程序。我们将首先讨论设置^(Settings)应用程序，然后讨论控制面板^{(Control Panel)}方法。

设置^(Settings)应用程序仅提供几个可以更改的默认应用程序。该列表包括视频播放器^{(Video Player)}、地图^(Maps)、照片查看器^{(Photo Viewer)}、邮件^(Mail)、音乐播放器^{(Music Player)}、日历^(Calendar)、浏览器^(Browser)等。程序或协议不可见。简而言之，设置^(Settings)应用程序仅提供几个选项，而控制面板^{(Control Panel)}中的列表更大。使用后者，您可以为更广泛的协议或服务更改默认程序。

Windows 10 将照片^(Photos)应用程序设置为默认的照片^(Photo)和图像查看器^{(Image Viewer)}。该示例告诉您如何将其更改为Windows Photo Viewer。您可以将其更改为您想要的任何内容——前提是设备上安装了相关的应用程序。

您可能需要更改与某些协议^(protocols)和文件扩展名^{(file extensions)}关联的默认程序。我们大多数人最终会将默认的PDF 查看器^{(PDF Viewer)}、浏览器或照片查看器^{(Photo Viewer)}更改为我们选择的另一个程序。如果您是其中之一，那么这篇文章将向您展示如何更改Windows 11/10中的默认照片查看器^{(Photo Viewer)}。

^(Change)通过Windows 设置^{(Windows Settings)}应用更改默认照片查看器^{(Photo Viewer)}

要更改Windows 10中的默认照片查看器^{(Photo Viewer)}：

1. 按Win+I打开“设置”^(Settings)应用并选择“系统^(System)” 。
2. 接下来，向下滚动到左窗格中的默认应用程序^{(Default Apps)}并单击它。
3. 选择照片查看器
4. 您将看到可以打开图像文件类型的程序列表。
5. 单击^(Click)Windows 照片查看器^{(Windows Photo Viewer)}或您想要的，保存设置并退出。

在 Windows 11 中设置默认应用程序，请执行以下步骤：

• Press Win+I打开Windows 设置^{(Windows Settings)}。
• 转到应用程序 > 默认应用程序。
• 向下滚动到底部。
  • 您甚至可以通过以下方式选择默认值
    • 应用
    • 文件类型
    • 协议

这就是你需要做的。下次系统需要启动浏览器时，它会打开您设置的默认浏览器。

^(Change)通过Windows 控制面板^{(Windows Control Panel)}更改默认照片查看器^{(Photo Viewer)}

如果您希望更改的默认协议在设置^(Settings)应用程序中不可用，您还可以使用控制面板^{(Control Panel)}更改Windows 10中的默认程序。

该方法与早期版本中的方法相同。Via Win+X菜单，打开控制面板^{(Control Panel)}，然后单击默认程序^{(Default Programs)}。

单击第一个选项，即设置您的默认程序。^{(Set Your Default Programs.)}

控制面板^{(Control Panel)}将找到已安装的应用程序和程序并显示列表。您将在左侧窗格中看到已安装程序的列表，右侧窗格将包含程序的描述，以及可让您将程序设置为它可以处理的文件/协议的默认值的选项

选择您希望设置为默认值的程序，然后单击将此程序^(Program)设置^(Set)为默认值^(Default)。这会将程序设置为它可以处理的文件和协议的默认值。

要进一步更改文件和协议，它可以处理，单击选择此程序的默认值。^{(Choose Defaults for this Program.)}

您将看到一个窗口，其中显示程序注册的文件扩展名和协议列表。选中您希望程序默认处理的文件和协议的复选框。单击保存^{(Click Save)}返回上一个屏幕并关闭控制面板^{(Control Panel)}

如果您收到此文件没有关联的程序来执行此操作消息，这篇文章将为您提供帮助。

The list includes Video Player, Maps, Photo Viewer, Mail, Music Player, Calendar, Browser, etc. The programs or protocols are not visible. In short, the Settings app offers just a few options whereas the list in Control Panel is bigger. Using the latter, you can change default programs for a wider range of protocols or services.

Windows 10 sets the Photos app as the default Photo and Image Viewer. The example tells you how to change it to Windows Photo Viewer. You can change it to anything you want – provided the related application is installed on the device.
