解决Windows防火墙不可识别无法开启的方法

1、点开始-设置-控制面板-安全中心-windows防火墙 无法启动windows防火墙设置

检查windows XP的Application Layer Gateway Service 服务是正确的

我的电脑右键管理→服务和应用程序→服务，找到Security Center. 是正确的

运行“gpedit.msc”命令打开组策略编辑器，依次展开“计算机配置→管理模板→网络连接→Windows防火墙” --服务是正确的

运行“services.msc”找到Windows Firewall/Internet Connection Sharing服务启用并为自动。

将Windows防火墙添加到注册表的方法

1. 将以下文本复制到记事本, 然后再保存文件作为 Sharedaccess.

3. 重新启动 Windows。

OK!Windows防火墙可以开启了!
