当你在使用Windows Server 2012 Core的时候，往往可能需要用到GUI界面来解决和调试设置。
但当你在使用Add-WindowsFeature的时候， 往往会得到以下报错：

Use the “source” option to specify the location of the files that are required to restore the feature. For more

解决方案很简单，你只需要在你的PC或者虚拟机内插入或加载上Windows Server 2012的光盘或iso文件，然后在Powershell中输入以下命令：
Add-WindowsFeature Server-Gui-Mgmt-Infra –Source wim:E:Sourcesinstall.wim:4 –Restart
服务器重启后，GUI界面就会展现出来，你可以通过GUI界面来添加或删除Roles和Features。
