1. 电脑所有软件都打不开怎么办
EXE关联错误！
1、打开“我的电脑”，进入菜单“工具”→“文件夹选项”→“文件类型，单击“新建”弹出“新建扩展名”对话框，在“文件扩展名”框中填入“exe”，接着单击“高级”，在“关联的文件类型”下拉框中选择“应用程序”，单击“确定”返回，最后单击“应用”后关闭对话框
2、如上面的方法不能解决，或应用那个按钮是灰的，那可以重启按F8选“命令提示符的安全模式”，然后在命令提示符下直接输入assoc .exe=exefile 或ftype exefile=%1%* 然后回车就OK了
实在不行从做系统吧！
2. 接受了个外挂、“我的电脑”打不开了、这是怎么回事啊
