 如果没有加速效果，请根据以下步骤进行排查     
 
 #### 1、请确认windows的代理设置处于勾选状态     
-如果已经是勾选状态，那么先取消勾选确定，然后再勾选确定，再尝试查看是否有加速效果（目前win7必需要手动开关一下）。  
+如果已经是勾选状态，那么先取消勾选确定，然后再勾选确定，再尝试查看是否有加速效果。  
  如何打开查看windows代理设置：    
  * win10: 开始->设置->网络和Internet->最下方代理      
  * win7: 开始->控制面板->网络和Internet->网络和共享中心->左下角Internet选项->连接选项卡->局域网设置
