可通过注册表文件、导入DLL组件或命令行三种方法恢复Windows 11旧版照片查看器：一、用.reg脚本批量关联图片格式；二、注册photoviewer.dll启用右键菜单；三、以管理员身份运行reg add命令添加系统级关联。
如果您在Windows 11中双击图片时默认打开的是新版“照片”应用，而希望重新启用简洁快速的旧版Windows照片查看器，则可能是由于系统默认关联被重置或注册表项缺失。以下是恢复该功能的多种可行方法：
本文运行环境：Surface Laptop 5，Windows 11 23H2。
一、通过注册表文件批量恢复图片格式关联
此方法利用预设的.reg脚本，一次性将常见图片扩展名（如.jpg、.png、.gif等）重新关联至旧版照片查看器的内部类标识，无需手动逐项配置，适配性强且操作统一。
1、在桌面空白处右键，选择“新建” → “文本文档”。
2、用记事本打开该文档，将以下完整代码复制粘贴进去：
Windows Registry Editor Version 5.00
; Associate .jpg files
[HKEY_CURRENT_USER\Software\Classes\.jpg]
@="PhotoViewer.FileAssoc.Jpeg"
; Associate .jpeg files
[HKEY_CURRENT_USER\Software\Classes\.jpeg]
@="PhotoViewer.FileAssoc.Jpeg"
; Associate .png files
[HKEY_CURRENT_USER\Software\Classes\.png]
@="PhotoViewer.FileAssoc.Png"
; Associate .gif files
[HKEY_CURRENT_USER\Software\Classes\.gif]
@="PhotoViewer.FileAssoc.Gif"
; Associate .bmp files
[HKEY_CURRENT_USER\Software\Classes\.bmp]
@="PhotoViewer.FileAssoc.Bmp"
; Associate .tiff files
[HKEY_CURRENT_USER\Software\Classes\.tiff]
@="PhotoViewer.FileAssoc.Tiff"
; Associate .ico files
[HKEY_CURRENT_USER\Software\Classes\.ico]
@="PhotoViewer.FileAssoc.Ico"
3、点击“文件” → “另存为”，将文件名设为enable_photo_viewer.reg，保存类型选“所有文件(*.*)”，编码选择UTF-8，保存到桌面。
4、双击刚保存的enable_photo_viewer.reg文件，在弹出的用户账户控制提示中点击“是”，确认导入注册表。
5、按Ctrl + Shift + Esc打开任务管理器，找到“Windows资源管理器”，右键选择“重新启动”，使关联立即生效。
二、导入核心DLL注册项启用查看器主体功能
仅关联扩展名不足以让“Windows照片查看器”出现在右键菜单中，还需注册photoviewer.dll组件及其Shell命令入口，此步骤补全系统对查看器的识别能力。
1、新建另一个文本文档，粘贴以下注册表内容：
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Applications\photoviewer.dll]
[HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell]
[HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell\open]
"MuiVerb"="@photoviewer.dll,-3043"
[HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell\open\command]
@=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,72,00,75,00,6e,00,64,00,6c,00,6c,00,33,00,32,00,2e,00,65,00,78,00,65,00,20,00,22,00,25,00,50,00,72,00,6f,00,67,00,72,00,61,00,6d,00,46,00,69,00,6c,00,65,00,73,00,25,00,5c,00,57,00,69,00,6e,00,64,00,6f,00,77,00,73,00,20,00,50,00,68,00,6f,00,74,00,6f,00,20,00,56,00,69,00,65,00,77,00,65,00,72,00,5c,00,50,00,68,00,6f,00,74,00,6f,00,56,00,69,00,65,00,77,00,65,00,72,00,2e,00,64,00,6c,00,6c,00,22,00,2c,00,20,00,49,00,6d,00,61,00,67,00,65,00,56,00,69,00,65,00,77,00,5f,00,46,00,75,00,6c,00,6c,00,73,00,63,00,72,00,65,00,65,00,6e,00,20,00,25,00,31,00,00,00
[HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell\open\DropTarget]
"Clsid"="{FFE2A43C-56B9-4bf5-9A79-CC6D4285608A}"
[HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell\print]
[HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell\print\command]
@=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,72,00,75,00,6e,00,64,00,6c,00,6c,00,33,00,32,00,2e,00,65,00,78,00,65,00,20,00,22,00,25,00,50,00,72,00,6f,00,67,00,72,00,61,00,6d,00,46,00,69,00,6c,00,65,00,73,00,25,00,5c,00,57,00,69,00,6e,00,64,00,6f,00,77,00,73,00,20,00,50,00,68,00,6f,00,74,00,6f,00,20,00,56,00,69,00,65,00,77,00,65,00,72,00,5c,00,50,00,68,00,6f,00,74,00,6f,00,56,00,69,00,65,00,77,00,65,00,72,00,2e,00,64,00,6c,00,6c,00,22,00,2c,00,20,00,49,00,6d,00,61,00,67,00,65,00,56,00,69,00,65,00,77,00,5f,00,46,00,75,00,6c,00,6c,00,73,00,63,00,72,00,65,00,65,00,6e,00,20,00,25,00,31,00,00,00
[HKEY_CLASSES_ROOT\Applications\photoviewer.dll\shell\print\DropTarget]
"Clsid"="{60fd46de-f830-4894-a628-6fa81bc0190d}"
2、以相同方式保存为register_photoviewer_dll.reg，编码为UTF-8，类型为“所有文件”。
3、双击执行该.reg文件，确认写入注册表。
4、重启资源管理器或注销当前用户后重新登录，右键任意图片即可在“打开方式”中看到Windows照片查看器选项。
三、使用命令行快速添加文件关联（管理员权限）
该方法绕过图形界面，直接调用reg add命令向系统级注册表写入关联项，适用于批量部署或脚本化运维场景，不依赖记事本与手动保存步骤。
1、右键开始按钮，选择“终端（管理员）”或“Windows PowerShell（管理员）”。
2、依次执行以下五条命令（每条单独回车）：
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Photo Viewer\Capabilities\FileAssociations" /v .jpg /d PhotoViewer.FileAssoc.Jpeg /f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Photo Viewer\Capabilities\FileAssociations" /v .png /d PhotoViewer.FileAssoc.Png /f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Photo Viewer\Capabilities\FileAssociations" /v .gif /d PhotoViewer.FileAssoc.Gif /f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Photo Viewer\Capabilities\FileAssociations" /v .bmp /d PhotoViewer.FileAssoc.Bmp /f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Photo Viewer\Capabilities\FileAssociations" /v .tiff /d PhotoViewer.FileAssoc.Tiff /f
3、执行完毕后，无需重启，立即生效。可尝试右键一张.jpg图片验证是否出现Windows照片查看器。
