最近有Win7系统用户反映，登录LOL的时候出现提示“LOL登录时遇到了一个预期之外的错误”，导致LOL登入失败，用户反复试了几次，结果都一样，这让用户非常烦恼，那么，Win7系统LOL登录时遇到了一个预期之外的错误如何解决呢？下面，我们一起往下看看。

　　方法/步骤

　　1、找到我们本机内的hosts文件，如果Hosts在指向的时候出现了问题，是会出现LOL登入时遇到了一个预期之外的错误这种问题的；

　　2、一般情况下路径为C：WindowsSystem32driversetc，找到这个文件然后清空文件内容，复制以下内容粘贴进去；

03# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

04#

05# This file contains the mappings of IP addresses to host names. Each

06# entry should be kept on an individual line. The IP address should

07# be placed in the first column followed by the corresponding host name.

08# The IP address and the host name should be separated by at least one

09# space.

10#

11# Additionally, comments (such as these) may be inserted on individual

12# lines or following the machine name denoted by a '#' symbol.

13#

14# For example:

15#

16# 102.54.94.97 rhino.acme.com # source server

17# 38.25.63.10 x.acme.com # x client host

18# localhost name resolution is handled within DNS itself.

19# 127.0.0.1 localhost

20# ::1 localhost
