我如何使我的应用成为Windows 10照片的默认应用

Question

我已将应用程序创建为exe。在Windows 10上，如果您打开设置应用->应用->默认应用，则可以选择应用作为照片，视频等的默认应用。我想为我的exe启用它。可以通过Windows注册表完成此操作吗？另外，我的应用程序可以打开非常规图像文件，例如webp和apng。我如何也从注册表中启用它。我将NSIS用于安装程序。非常感谢

遵循Registering an Application for Use with Default Programs的文档：

!define MyAppUniqueName "MyCompany.MyApp"
!define MyCapabilitiesKey "Software\MyCompany\MyApp\Capabilities"
!define MyProgId "MyCompany.MyApp.File"

Section
WriteRegStr ShCtx "Software\Classes\${MyProgId}\shell\open\command" "" '"$InstDir\myapp.exe" "%1"'

WriteRegStr ShCtx "${MyCapabilitiesKey}" "ApplicationName" "Blah"
WriteRegStr ShCtx "${MyCapabilitiesKey}" "ApplicationDescription" "Blah blah blah"
WriteRegStr ShCtx "${MyCapabilitiesKey}\FileAssociations" ".webp" "${MyProgId}
WriteRegStr ShCtx "${MyCapabilitiesKey}\FileAssociations" ".apng" "${MyProgId}"
WriteRegStr ShCtx "Software\RegisteredApplications" "${MyAppUniqueName}" "${MyCapabilitiesKey}"
SectionEnd

Section Uninstall
DeleteRegKey ShCtx "Software\Classes\${MyProgId}"

DeleteRegValue ShCtx "Software\RegisteredApplications" "${MyAppUniqueName}"
DeleteRegKey ShCtx "${MyCapabilitiesKey}"
SectionEnd
