最近有Win7系統用戶反映，登錄LOL的時候出現提示“LOL登錄時遇到了一個預期之外的錯誤”，導致LOL登入失敗，用戶反復試了幾次，結果都一樣，這讓用戶非常煩惱，那么，Win7系統LOL登錄時遇到了一個預期之外的錯誤如何解決呢？下面，我們一起往下看看。

方法/步驟

1、找到我們本機內的hosts文件，如果Hosts在指向的時候出現了問題，是會出現LOL登入時遇到了一個預期之外的錯誤這種問題的；

2、一般情況下路徑為C：WindowsSystem32driversetc，找到這個文件然后清空文件內容，復制以下內容粘貼進去；

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. Each06# entry should be kept on an individual line. The IP address should07# 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 one09# space.10#11# Additionally, comments (such as these) may be inserted on individual12# lines or following the machine name denoted by a '#' symbol.13#14# For example:15#16# 102.54.94.97 rhino.acme.com # source server17# 38.25.63.10 x.acme.com # x client host18# localhost name resolution is handled within DNS itself.19#127.0.0.1 localhost20#::1 localhost復制代碼# 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.

3、更改完Hosts文件后找到我們的網絡連接，然后找到自己當前使用的網絡連接（本地連接），右鍵選擇屬性，找到下圖所標記的協議；

4、把DNS更改為公網DNS大家可以參考下今年評估的DNS排名，選擇你所需要的DNS作為固定DNS；

5、最后只需要重置下網絡協議即可，這里我們可以使用本機自帶的DOS命令進行重置也可以使用第三方軟件進行重置；

6、這樣就可以順利登入游戲了，導致這種情況出現的原因一般為高峰期、更新后、或者有些人被封號了也會導致這類情況的出現，被封號這種情況是無法通過重置網絡設置解除的。

以上就是Win7系統LOL登錄時遇到了一個預期之外的錯誤的具體解決方法，按照以上方法進行操作，相信再次登入LOL的時候，就能正常登入了。
