大家都知道，WIN系统自带的看图工具比较鸡肋。博主在给系统安装上了Honeyview便携版后，需要进行默认程序的切换，这时候才发现选择打开方式到选择其他应用时没有反应，这个问题该如何解决？

1、新建文本文档，复制以下内容，然后另存为1.reg到桌面，保存类型：所有文件(*.*)，编码格式：ANSI ；

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Unknown\shell\openas]
@=hex(2):40,00,25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,\
00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,73,00,\
68,00,65,00,6c,00,6c,00,33,00,32,00,2e,00,64,00,6c,00,6c,00,2c,00,2d,00,35,\
00,33,00,37,00,36,00,00,00
"MultiSelectModel"="Single"
[HKEY_CLASSES_ROOT\Unknown\shell\openas\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,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,4f,00,70,00,\
65,00,6e,00,57,00,69,00,74,00,68,00,2e,00,65,00,78,00,65,00,20,00,22,00,25,\
00,31,00,22,00,00,00
"DelegateExecute"="{e44e9428-bdbc-4987-a099-40dc8fd255e7}"

2、新建文本文档，复制以下内容，然后另存为2.reg到桌面，保存类型：所有文件(*.*)，编码格式：ANSI ；

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Unknown\shell\OpenWithSetDefaultOn]
"MultiSelectModel"="Single"
"ProgrammaticAccessOnly"=""
[HKEY_CLASSES_ROOT\Unknown\shell\OpenWithSetDefaultOn\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,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,4f,00,70,00,\
65,00,6e,00,57,00,69,00,74,00,68,00,2e,00,65,00,78,00,65,00,20,00,2d,00,6f,\
00,76,00,65,00,72,00,72,00,69,00,64,00,65,00,20,00,22,00,25,00,31,00,22,00,\
00,00
"DelegateExecute"="{e44e9428-bdbc-4987-a099-40dc8fd255e7}"

3、在桌面分别双击打开这两个reg文件。

至此问题解决。

怕麻烦的可以直接下载附件，解压后直接执行就OK了！
