Win7电脑在登录LOL的时候出现登入时遇到了一个预期之外的错误怎么办？虽然微软已经出了许多的新版操作系统，但是对于一些硬件配置较低的用户还是使用win7系统。而最近有的用户就反应了这个问题，那么下面小编就带着大家一起看一下吧！
操作方法：
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；
01# Copyright (c) 1993-2009 Microsoft Corp.
02#
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

# 127.0.0.1 localhost
# ::1 localhost
3、更改完Hosts文件后找到我们的网络连接，然后找到自己当前使用的网络连接（本地连接），右键选择属性，找到下图所标记的协议；
4、把DNS更改为公网DNS大家可以参考下今年评估的DNS排名，选择你所需要的DNS作为固定DNS；
5、最后只需要重置下网络协议即可，这里我们可以使用本机自带的DOS命令进行重置也可以使用第三方软件进行重置；
6、这样就可以顺利登入游戏了，导致这种情况出现的原因一般为高峰期、更新后、或者有些人被封号了也会导致这类情况的出现，被封号这种情况是无法通过重置网络设置解除的。
以上就是Win7系统LOL登录时遇到了一个预期之外的错误的具体解决方法，按照以上方法进行操作，相信再次登入LOL的时候，就能正常登入了。
