android studio 无法启动解决。启动 android studio 时显示启动画面，但一直无法继续

可以安装 IntelliJ IDEA Edition 启动时提示 bind 错误。

因为 IDEA需要在端口6942~6991间找到一个可用端口并绑定(bind) 。但是这些端口被 Hyper-V 占用。有两种解决方案

1. 执行
   ```netsh winsock reset ```

2. 让 hyper-v 在占用端口中排除一个端口， 可能要安装 KB4074588

   @veqryn the workaround worked for me, the steps are:
   
   Disable hyper-v (which will required a couple of restarts)
   dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
   
   When you finish all the required restarts, reserve the port you want so hyper-v doesn't reserve it back
   netsh int ipv4 add excludedportrange protocol=tcp startport=<端口号> numberofports=1
   
   Re-Enable hyper-V (which will require a couple of restart)
   dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All
   
   when your system is back, you will be able to bind to that port successfully.
   
   请把端口号改成6942~6991间的任一个数字
