Hosts文件可以帮助快速访问某个网站，Win7系统Hosts文件还可以屏蔽网站，重新定向网站域名等，但也有网友遇到了win7系统Hosts文件异常的问题，那么这是怎么回事？要怎么解决呢？
一般来讲Windows XP/2003/Vista/2008/7/8/8.1/10用户Hosts文件是在：C:\Windows\System32\drivers\etc
大家可以直接根据上述路径进入，也可Win+R后输入：C:\Windows\System32\drivers\etc
Hosts文件修复方法：将hosts文件复制到桌面，用记事本打开；删除记事本的全部内容，将以下内容复制后放入文件然后保存：
# copyright (c) 1993-1999 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
127.0.0.1 localhost
127.0.0.1 localhost
