在Windows 11中，打开Press Win+I打开Settings > Apps > Default应用程序，然后单击按文件类型^{(Choose default by file type)}或链接类型^{(link type)}选择默认值。

Windows 10用户应通过WinX Menu > Apps > Default设置^(Settings)，然后单击按文件类型或协议选择默认应用程序^{(Choose default apps by file type or by Protocol)}链接。

导出或导入文件关联^{(Import File Association)}设置列表

一旦您手动配置了所有文件关联，如果您愿意，您还可以导出和保存这些设置。如果您正在运行由多台计算机组成的网络并且需要在所有计算机上部署相同的设置，这也非常有用。

要导出列表，请打开提升的命令提示符^{(Command Prompt)}，键入以下内容，然后按 Enter^(Enter)。

Dism.exe /Online /Export-DefaultAppAssociations:C:\FileAssociations.xml

您将在 C 驱动器上看到一个FileAssociations.xml文件。^{(FileAssociations.xml)}
