解决 internet connection sharing 启动不了

1、确认Windows Firewall服务是否启动(有异常可参考下面)

a.打开注册表，找到HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesSharedAccess; 

b.右键SharedAccess，选择“权限”; 

c.单击“添加”. 

d.在“输入对象名称来选择”下方的文本框中输入“NT SERVICEmpssvc”，然后点击右侧的“检查名称”，此时文本框中的内容变为“MpsSvc”; 

e.单击“确定”; 

f.设置“MpsSvc”的权限，勾选“完全控制”为“允许”; 

g.单击“确定”。 启动服务

2、导入注册表
