WIN7更新后双击打不开盘符和文件夹。第一项是资源管理器...

Answer 1

你好，

这应该是文件夹的关联出现了问题，请尝试以下：

1.单击“开始”按钮并在搜索条中输入“cmd”，并右键搜索结果中的“命令提示符”选择“以管理员身份运行”;
2.在“管理员：命令提示符”窗口中输入：Assoc folder=folder
若问题仍然存在，请将下面的注册表项编辑命令复制到TXT文档中并另存为.REG注册表项文件，双击导入注册表：
Windows Registry Editor Version 5.00

另外，若当前没有显示已知文件扩展名则无法将TXT文档有效地更改为REG注册表项文件，请通过在资源管理器中单击“组织”-“文件夹选项”-“查看”对话框来显示已知文件扩展名，再进行修改。
