这些问题可能需要重新安装操作系统。Microsoft不能保证能够解决这些问题，修改注册表需要您自担风险。
另外：要将Windows防火墙项添加到注册表，请按照下列步骤操作：
1.将以下文本复制到记事本，然后保存文件为 Sharedaccess.reg:
Windows Registry Editor Version 5.00
[-HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\SharedAccess]　[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\SharedAccess]

”NextInstance”=dword:00000001
2.双击 Sharedaccess.reg,将此文件的内容合并到注册表可创建防火墙项。
3.重新启动 Windows.
4.单击开始-运行，输入cmd,确定。
5.在命令提示符，键入以下命令：Netsh firewall reset ,回车。
6.单击开始-运行，输入firewall.cpl,确定。
7.配置与要使用 Windows 防火墙设置。
【电脑防火墙点击无反应怎么解决 win7防火墙打不开怎么办】当然，防火墙本身也有其局限性，即不经过防火墙的入侵，防火墙则是无能为力的，如被保护网络中通过SLIP和PPP方式直接与因特网相连的内部用户，则会造成安全隐患。因此,在一个实际的网络运行环境中，仅仅依靠防火墙来保证网络的安全显然是不够，此时，应根据实际需求采取相应的安全策略。
