Windows10中可以通过修改注册表的方法找回照片查看器。 新建ton.reg注册表文件，内容如下： Windows Registry Editor Version 5.00 ; Change Extension's File Type [HKEY_CURRENT_USER\Software\Classes\.jpg] @="PhotoViewer.FileAssoc.Tiff" ; Change Extension's File Type [HKEY_CURRENT_USER\Software\Classes\.jpeg] @="PhotoViewer.FileAssoc.Tiff" ; Change Extension's File Type [HKEY_CURRENT_USER\Software\Classes\.gif] @="PhotoViewer.FileAssoc.Tiff" ; Change Extension's File Type [HKEY_CURRENT_USER\Software\Classes\.png] @="PhotoViewer.FileAssoc.Tiff" ; Change Extension's File Type [HKEY_CURRENT_USER\Software\Classes\.bmp] @="PhotoViewer.FileAssoc.Tiff" ; Change Extension's File Type [HKEY_CURRENT_USER\Software\Classes\.tiff] @="PhotoViewer.FileAssoc.Tiff" ; Change Extension's File Type [HKEY_CURRENT_USER\Software\Classes\.ico] @="PhotoViewer.FileAssoc.Tiff" 保存后，双击运行即可，然后右键打开方式中即可看到照片查看器。
