Answer 1

1、系统默认的用户HOSTS文件是在“c:\windows\system32\drivers\etc，默认文件是在系统盘。

2、输入Win+R组合键，弹出运行栏弹窗，如图所示。

3、然后在运行文本框输入c:\windows\system32\drivers\etc命令，点击确定按钮，如图所示。

4、然后进入到默认系统hosts文件夹下，将其复制，然后用记事本打开。

5、 然后用恢复Hosts文件的代码进行替换，打开记事本的内容。

6、修改之后，然后进入到c:\windows\system32\drivers\etc文件，替换以前的hosts文件。

为了防止以后被修改，可以右键文件属性，安全里面勾选只读，这样以后就无法修改内容了，记事本内容全部清空，复制下面的内容保存：
# Copyright (c) 1993-2009 Microsoft 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

方法一 、复制法

这是一种最简单的方法，就是先将hosts文件复制到别的地方，修改完了再覆盖回来就搞定了。中间会提示目标文件夹拒绝访问，需要提供管理员权限，点击继续即可。

方法二 、记事本更改法

1、在win7开始菜单中找到“记事本”，并右击它，选择“Run as administrator”(以管理员运行);

2、接着即可用记事本打开hosts文件，hosts文件路径的是C:\Windows\System32\drivers\etc\hosts；

3、打开hosts文件之后，再写好自己的hosts语句，直接保存就可以了。

127.0.0.1 localhost

上述文字是原件内容，实际上#的都是注释文字，起作用的就最后行。
