请问win7系统文件记事本打开方式关联了怎么解除

开始菜单搜索输入 regedit 进注册表

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts
选择要修改的打开方式菜单的扩展名
然后把扩展名那个文件夹 删掉
重启

把下面***为界线的内容复制到记事本上,保存为1.reg(不包括*号)

重启开机按f8,选择带命令行的安全模式,----进入安全模式下在命令提示符输入explorer.exe回车.再双击1.reg,把注册表文件导入,重启看能不能改回来

注意:复制下面内容里windows registry editor version 5.00这一行必需是第一行,上面一定不可以有空行
