新建一个TXT文本文档，把以下代码复制粘贴到其中： 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\.pcx] @="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"
然后把该文本文档重命名为 Windows_photo_viewer.reg （或任意名称），然后双击运行该 reg 注册表文件把数据导入注册表中即可。
或者直接下载下面的文件，然后运行。
