从Win10开始，直到现在Win11，Windows系统默认的看图App都存在一个重大缺陷——色彩管理，在Win7中，就不存在这样的问题。Win7系统的照片查看器使用Win32构建，对色彩管理有着比较好的支持。于是问题来了，在Win10/Win11中这个Win7版的照片查看器默认是找不到的，要如何重新将它找回来？可以试试下面的方法！

方法一：添加Win7照片查看器注册表信息

1、首先，我打开记事本，将以下文本复制进去。

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、接着，点击文件-另存为，将其另存为后缀名为.reg的注册表文件。

3、然后，双击运行这个注册表文件，向注册表导入信息，这个时候Win7版本的照片查看器其实就已经回来了。

方法二：设置图片默认打开方式（以Win11为例，Win10类似）

1、右键点击任一图片文件，选择打开方式，点击选择其他应用：

2、点击更多应用并确定：

3、选择Windows照片查看器并勾选始终使用此应用打开并确定：

4、这时可以看到经典的照片查看器已经回来了。
