win10解决没有照片查看器的办法

新建一个.txt格式的文本文档，将下列代码复制进去：

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"

然后选择另存为reg.reg ,名称可以自己取，但是文件后缀名要是.reg

然后修改默认为图片查看器就可以了
