C:尀Windows尀System32尀drivers尀etc host文件误删， 谁有啊 win7 32位的 拜托啦

　　hosts文件本质是一个文本文件，默认的hosts文件内容全部为注释，没有任何功能，所有直接建立一文本文件，修改名称为hosts即可，操作如下：

　　1、按win+r，输入C:\Windows\System32\drivers\etc，点击确定；

　　2、文件夹窗口空白处右击，选择新建--文本文件；

　　3、右击该文件，选择重命名，删除原有文件名和后缀，输入hosts，弹出对话框点击是即可。

# 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

这就是系统最初的hosts文件，什么用都没有，之后安装的应用程序修改它之后，它才起作用。

新建一个 文本文件 写上 127.0.0.1 localhost
保存
改名为 host ,放在C:\Windows\System32\drivers\etc
