如何修复损坏的host文件

1、从功能上来说，host文件是一稍僚敉视个电脑内置的DNS的列表，优先级高于DNS，是IP地址和域名的对应，右键选择打开方式为文本文档，即可打开并编辑！

2、而host文件的位置，其位于C盘的windows/system32/drivers/etc中，如图所示。

3、当然，按下windows+R打开运行，输入c:windowssystem32driversetc按回车，如图所示。

4、接下来，我们选择找到的hosts文件后将其复制到桌面，用记事本打开。

5、然后，删除记事本的全部内容，将以下内容复制到文件中然后保存：# Copyright (c) 1993-2009 M足毂忍珩icrosoft Corp.## This is a sample HOSTS file used by Microsoft TCP/IP for Windows.## This file contains the mappings of IP addresses to host names. Each# entry should be kept on an individual line. The IP address should# be placed in the first column followed by the corresponding host name.# The IP address and the host name should be separated by at least one# space.## Additionally, comments (such as these) may be inserted on individual# lines or following the machine name denoted by a '#' symbol.## For example:## 102.54.94.97 rhino.acme.com # source server# 38.25.63.10 x.acme.com # x client host# localhost name resolution is handled within DNS itself.# 127.0.0.1 localhost# ::1 localhost

6、然后将修改好的hosts文件放到C盘windows/system32/drivers/etc中来替换以前的hosts文件，就可以完成修复了。
