the Internet is becoming more and more insecure today, many users have listed the firewall as one of the necessary software for installation, and major security vendors in order to attract users Eyeballs also make their own firewalls more colorful. In contrast, the Windows 7 system's own firewall is simple in appearance, but after years of development and improvement, it has now existed as a standard personal firewall in the system.
New startup method and repair
In the startup mode, the Windows 7 firewall will no longer need to create an empty MMC and add a management unit, which is easier to operate than the previous version. Just click on the Advanced Settings Connection “Start Menu/Control Panel/System and Security/Windows Firewall> in the left panel to open the firewall configuration interface.

In the shortcut menu, select the “New Rule” command. Here, the automatic update program of Thunder is taken as an example. If you want to prohibit the automatic upgrade program of Thunder from accepting any data, the user will be asked to select the rule type in the pop-up "New Inbound Rules Wizard" interface, the user can target the application and port. , service selection, after selecting “ application & rdquo;, select the "ThunderLiveUD.exe" file under the Thunder folder.
After the selection is made, continue to choose the connection method to connect to the network. Win 7 provides users with three connection methods:
Allow connection: The program or port can be connected to the network under any circumstances.
Only secure connections are allowed: Programs or ports are allowed to connect to the network only if they are protected by IPSec.
Blocking Connections: Prevents this program or port from connecting to the network in any state.
