Win7无法登录LOL提示遇到了一个预期之外的错误如何解决
1、首先修改本机中的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：\Windows\System32\drivers\etc，找到这个文件然后清空文件内容，复制以下内容粘贴进去；
# 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

# 127.0.0.1 localhost
# ::1 localhost
3、更改完Hosts文件后在网络共享中心找到当前的网络连接，使用鼠标右键单击并选择属性，如下图所示找到IPv4并双击打开；
4、在弹出的属性窗口中把DNS更改为公网DNS大家可以如果你不知道怎么填写，可以参照下图中的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；
以上就是关于Win7无法登录LOL提示遇到了一个预期之外的错误如何解决的全部内容了，使用上面的方法就可以帮助我们正常登陆LOL了。
