近期使用android sdk manager升级android sdk时，发现国内有名的东软镜像居然没有android的支持了。在网上到处都是采用mirrors.neusoft.edu.cn解决升级问题。还有人列出了add-ons list中的东软部分：        http://mirrors.neusoft.edu.cn/android/repository/addon-6.xml       http://mirrors.neusoft.edu.cn/android/repository/addon.xml      http://mirrors.neusoft.edu.cn/and

Windows Server 2016中安装PHP Manager、ARR3.0或者URL Rewrite 2.0无法成功的解决办法 如图： 无法安装原因都是这几个工具无法识别10.0这个版本，可以修改注册表来先完成安装，然后再改回去 PHPManager的修改方法如下： 打开注册表工具（运行Regedt32），找到： HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\Parameters 看MajorVersion 是DWORD值，它的值十进制是10，改成9 ARR3.0或者URL Rewrite 2.0的修改方法如下：
