In the presence of an always active Internet connection, the user is not recommended to turn off the firewall functions that block malicious files and software.

If anti-virus software is installed on the computer, it is recommended to disable Windows Firewall to avoid conflicts between them and, as a rule, incorrect operation of both security programs.

With the Windows Firewall notification feature enabled, when a malicious or suspicious program tries to run, the system prompts the user to allow or block the application. When the notification system is turned off, the firewall automatically blocks the launch of suspicious applications.

A firewall is designed to protect your PC from attacks by hackers or malware over the Internet or a local network. It is installed on all devices under Windows control 10. But you need to know how to turn on the Windows 10 firewall and how to configure it correctly.

Where is

As in previous versions of the operating system, in Windows 10 the utility is located in the Control Panel.

Another option to launch it is to enter the word "firewall" in the "Run" window. In the list that opens, it is in first place.

Healthy! You can run the utility with the command: firewall.cpl, which you type in the Run box.

How to turn on

By default, this security utility in Windows 10 is always enabled. But if you see that it does not work, you need to activate it.

Setting

To work correctly, the utility must be configured correctly. Therefore, very rarely users use its default settings.

Adding exclusions

Adding exclusions to Windows 10 Defender will allow you not to turn off the utility completely for the full operation of the program that it blocks. Therefore you will be able to run desired application and do not lose a reliable protector.

Opening ports

To increase the security of your computer, the utility blocks all connections on non-primary ports. But if the user needs to connect, for example, an ftp server, traffic will appear on port 20 and 21. Therefore, they need to be opened.

You can create a rule for an outgoing connection in the same way in the "Rules for outgoing connections" section.

Shutdown

You may need to disable a security utility if it interferes with the operation of a certain program, and adding it to the exceptions does not help. It is also better to disable Windows 10 Defender if you have installed another firewall on your computer.

Windows Firewall prevents the bad guys around the clock and malware break into the computer. It implements this approach by checking incoming data from the network. The firewall then decides whether to block the incoming information or let it through. This utility is not like a regular antivirus, it blocks access to worms and hackers. This is how it looks on the diagram.

Activation and deactivation

• We open the firewall itself, this can be done through the search.
• You can also get into the Windows firewall through the Control Panel.
• In the left part of the window there is an item Enable and disable ....
• This item must be enabled to disable or enable the firewall.

If the user's computer is connected to a local network, then the firewall is unlikely to be turned off without the knowledge of the administrator.

Parameters

The setting of such a utility has only four parameters for correcting work. To get to their changes you need:

• Open the firewall itself as described above.
• Select the Enable/Disable… item.
• Next, a list of options will open.

The parameter setting consists of several items, each of which provides a certain functionality:

• Enable Windows Firewall. By default, this utility is always enabled. This blocks many applications from receiving data from the network. To disable this option and give air to programs, you need to add them to a special list:

• Block all incoming connections, including for applications specified in the list of allowed programs. This is a setting that closes all possible ways connection to a computer. It is especially useful to use it in unfamiliar places where the network connection is not guaranteed to be secure. At the same time, it will still be possible to watch almost all pages on the Internet, receive mail and send it, and work with instant messages.
• Notify when Windows Firewall is blocking a new app. This is a notification system, when some application is blocked, the axis displays a message about this event.
• Disable Windows Firewall. This is a very dangerous button that opens the way for worms and all that bad stuff that accumulates on the Internet and waits for an opportunity to capture users' personal data.

Opening the port

To play games over the Internet, for example, you can create a special exception to the rules for some application. We add it to the list, as described above, but if this does not work out, then setting the port will help. This port is open all the time, so be aware of that.

• Select Advanced options.
• In the left part of the window, select Windows Firewall with Advanced Security and click on the Inbound Rules link.
• Click on Create Rule.
• We follow the prompts on the screen.

Windows Firewall is a firewall built into the operating system, part of the Security Center, which is responsible for programs accessing the network.
