新建一个文本文档.txt文件
将下面的代码复制到文件里，将文件重命名为“1.reg”

1. 
   
2. <div>Windows Registry Editor Version 5.00
   
3. 
   
4. [HKEY_CLASSES_ROOT\Unknown\shell\openas]
   
5. @=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,\
   
6. 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,\

8. 00,33,00,37,00,36,00,00,00
   
9. "MultiSelectModel"="Single"

12. [HKEY_CLASSES_ROOT\Unknown\shell\openas\command]
    
13. @=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,\

再建立一个文本文档.txt文件
将下面的代码复制到文件里，将文件重命名为“2.reg”

1. 
   
2. <div>Windows Registry Editor Version 5.00
   
3. 
   
4. [HKEY_CLASSES_ROOT\Unknown\shell\OpenWithSetDefaultOn]
   
5. "MultiSelectModel"="Single"
   
6. "ProgrammaticAccessOnly"=""
   
7. 
   
8. 
   
9. [HKEY_CLASSES_ROOT\Unknown\shell\OpenWithSetDefaultOn\command]
   
10. @=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,\

14. 00,00
    
15. "DelegateExecute"="{e44e9428-bdbc-4987-a099-40dc8fd255e7}"</div>

将“1.reg”与“2.reg”依次运行，即可修复电脑右键菜单中的“打开方式”消失的问题。
