A simple solution to the problem that the firewall can not be started

With the development of network technology, the Internet has entered thousands of households. Therefore, the security of the network will become the most concerned issue. Currently, a more effective way to protect internal networks from external intrusions is firewall technology. Many netizens will ask what is a firewall?

In fact, a firewall is a system or a group of systems that enforce access control policies between networks. The actual way of real firewalls is different, but in principle, firewalls can be considered as such a pair of mechanisms. To be fair, firewalls are a bastion to protect computer operating systems, which can keep viruses out of thousands of miles. However, users often find that Windows Firewall cannot be started. This system brings a lot of security risks. The following small series will give users some solutions about Windows Firewall failing to start.

Second, the security center is closed

Firewall enabled options become gray, can not be enabled And with the prompt " Due to security considerations, some settings are controlled by Group Policy"
