However, such complexes cost several thousand dollars and “mere mortals” (including most system administrators) make do with ready-made software solutions such as Windows 7 Firewall.

Essentially, the firewall performs the functions of a checkpoint on or where it is installed.

Which packet to skip and which to block? Brandmauer determines with the help of rules laid down in it in advance. These rules vary depending on the software version, and users can also customize their rules during operation.

The need to create own rules for the firewall occurs provided that the firewall is enabled, but special permissions are required for some programs (primarily for incoming traffic). Restrictions may also be placed on outgoing traffic.

Hello! Glad to be with you again. I haven’t written anything for almost a week because I got involved in an adventure called “Spanish Money: To Freedom!” Those who know will understand me. Today I want to tell you about disabling the firewall in Windows 7/10. First, according to tradition, a little education.

What is a firewall and why should you disable it?

A firewall, also known as a firewall, also known as a firewall (hereinafter, these words will be used as synonyms) protects our computer from external intrusions and from information leakage into the network. In general, the word firewall translated from English means “wall from fire,” and firewall is the same thing, only in German, if I’m not mistaken.

Normally, this should be separate software product, powerful program! For example Outpost Firewall, Comodo Firewall or Norton Internet Security. But third party programs, as a rule, are bulky and take up a lot system resources and require a lot of knowledge and nerves to set up. Therefore, most users are satisfied with the firewall built into Windows. I’ll say right away that disassembling these programs is not the topic of the article; to receive more information, subscribe to blog updates.

However, almost all popular ones have a built-in firewall. So, if you have installed such an antivirus, then you may have a completely legitimate desire to disable the built-in firewall in Windows. Also when various problems with or vice versa - with access to the computer from the Internet, you can try to disable the firewall to check if it is the problem. In some cases, the firewall may affect .

Disable Windows 7/8/10 Firewall

I’ll say right away that compared to the Windows XP firewall, the seven has enough reliable protection, and you should only turn it off if you know exactly what it was exchanged for and what you will get from it.

If you still decide to disable the Windows Firewall, then I will show you how to do it simply step by step:

Required here small retreat. The fact is that Windows 7-10 distinguishes between Home (Work) networks and Community networks. It’s easy to guess that home and work networks are local networks under your control, and public ones are the Internet. For home networks, they usually do not turn on a firewall, even if there is no alternative, just so as not to have problems with access. For example, if you have a computer or media player connected to home network, then to avoid problems with access to computer resources, it is better to disable the firewall in relation to home networks.

If you installed another program or antivirus with a built-in firewall, then you must disable the Windows 7 firewall for all networks! This is necessary because two firewalls should not be running on a computer at the same time, just as two antiviruses should not be installed. Otherwise, they will conflict with each other, which can lead to severe slowdown of the computer or even freeze. It's like letting your mother-in-law and daughter-in-law share the same kitchen.

However, most programs with a built-in firewall replace the Windows firewall and the window will say “These settings are managed by the ESET vendor application Internet Security", i.e. indicates the program that you have installed.

In this case, you cannot disable anything from the control panel; to do this, you need to open the program settings. For example, I have NOD32, and to disable the protection you just need to click right click on the application icon in the system tray and select “Suspend the firewall (allow all traffic)”

Most other antiviruses do the same.

How can I just turn off the service?

In principle, after the actions taken, the protection no longer works. But some people simply disable a service in Windows called Firewall. In this case, all firewall functions are disabled, regardless of its settings. To disable a service:

• Go to “Start -> Control Panel -> System and Security -> Administrative Tools -> Services” and find "Windows Firewall" in the list.
• Right-click on it and select "Stop"
• To prevent the firewall from turning on after a reboot, right-click again and select “Properties”, and then change the startup type to “Disabled”

The firewall is now disabled and next boot will not turn on. Accordingly, to enable the Windows 7,8,10 firewall, carry out all actions in the reverse order

Remember! That by disabling the firewall completely, without having any other alternative, you are putting your computer and all the data on it at risk!

If there are any problems with access that disappear after disabling the firewall, then it is better to figure it out once and configure the service correctly than to disable it forever.

From this article you learned what the Windows 7 firewall is, how to disable it correctly, why it is needed at all, and what it can be fraught with. possible in reverse order. Share this article with your friends, they will thank you!

And this is dessert for today, Norman the dog learned to ride a bike!

Windows Firewall controls application access to the network. Therefore, it is a primary element of system protection. It is enabled by default, but various reasons it could have shut down. These reasons can be either system failures or a purposeful stop of the firewall by the user. But the computer cannot remain unprotected for long. Therefore, if an analogue was not installed to replace the firewall, then the issue of re-enabling it becomes relevant. Let's see how to do this in Windows 7.

The procedure for turning on the firewall directly depends on what exactly caused this OS element to be turned off, and how it was stopped.

Method 1: Tray icon

The easiest way to enable the built-in Windows firewall when standard version To disable it, use the Action Center icon in the tray.

After completing this procedure, the protection will be launched.

Method 2: Help Center

You can also enable the firewall by directly visiting the Action Center via the tray icon.

Method 3: Control Panel subsection

The firewall can be launched again in the subsection of the Control Panel, which is dedicated to its settings.

1. Click "Start". Follow the inscription "Control Panel".



2. Let's move on "System and Security".



3. After going to the section, click on "Windows Firewall".

   

   You can move to the firewall settings subsection by using the tool’s capabilities "Run". Initiate launch by typing Win+R. In the area of ​​the window that opens, enter:

   Click "OK".



4. The firewall settings window is activated. It says that the firewall is not using the recommended settings, that is, the defender is disabled. This is also evidenced by the icons in the form of a red shield with a cross inside, which are located next to the names of network types. There are two methods you can use to enable it.

   

   The first one involves simply clicking on “Use recommended parameters".

   

   The second option allows you to make fine tuning. To do this, click on the inscription "Turn Windows Firewall on or off" in the side list.



5. There are two blocks in the window, which correspond to public and home network connection. In both blocks the switches should be set to position "Turn on Windows Firewall". If you wish, you can immediately determine whether it is worth activating the blocking of all incoming connections without exception and reporting when the firewall blocks a new application. This is done by checking or unchecking the corresponding parameters. But, if you are not very versed in the meaning of these settings, then it is better to leave them at default, as shown in the image below. After completing the settings, be sure to click "OK".



6. After this, you return to the main firewall settings window. There it is reported that the defender is functioning, as evidenced by the green shield icons with checkmarks inside.

Method 4: Enable the service

You can also start the firewall again by enabling the corresponding service, if the shutdown of the defender was caused by its intentional or emergency stop.

1. To go to the Service Manager, you need to go to the section "System and Security" Control panels click on the name "Administration". How to get to the system and security settings section was discussed when describing the third method.



2. In the set of presented system utilities in the administration window, click on the name "Services".

   

   You can open the dispatcher using "Run". Launch the tool ( Win+R). Enter:

   Click "OK".

   

   Another option for getting to the Service Manager involves using the Task Manager. Let's call it: Ctrl+Shift+Esc. Go to the section "Services" Task Manager, and then click on the button with the same name at the bottom of the window.



3. Each of the three actions described above results in a call to the Service Manager. We look for the name in the list of objects "Windows Firewall". Let's highlight it. If the element is disabled, then in the column "State" the attribute will be missing "Works". If in the column "Startup type" attribute set "Automatically", then the defender can be launched by simply clicking on the inscription "Start service" on the left side of the window.

   

   If in the column "Startup type" worth attribute "Manually", then you should do it a little differently. The fact is that we, of course, can enable the service as described above, but when restart protection will not start automatically on your computer, since the service will have to be turned on manually again. To avoid this situation, double-click on "Windows Firewall" in the list with the left mouse button.



4. The properties window opens in the section "General". In the area "Startup type" from the expanded list instead "Manually" choose an option "Automatically". Then press the buttons sequentially "Run" And "OK". The service will start and the properties window will close.

If in the area "Startup type" worth an option "Disabled", then the matter becomes even more complicated. As you can see, there is not even an inscription to enable on the left side of the window.

Method 5: System Configuration

Stopped service "Windows Firewall" can also be started using the system configuration tool if it was previously disabled there.

1. To go to the desired window call "Run" by pressing Win+R and enter the command into it:

   Click "OK".

   

   You can also be in the Control Panel in the subsection "Administration", select from the list of utilities "System Configuration". These actions will be equivalent.



2. The configuration window opens. We move in it to the section called "Services".



3. Going to the specified tab in the list, we look for "Windows Firewall". If this element was turned off, there will be no check next to it, and also in the column "State" attribute will be specified "Disabled".



4. To enable it, put a tick next to the name of the service and click sequentially "Apply" And "OK".



5. A dialog box appears telling you that you must restart your computer for the settings changes to take effect. If you want to enable protection immediately, then click on the button, but first close all running applications, and also save unsaved files and documents. If you do not think that installing protection with the built-in firewall is necessary immediately, then in this case click "Exit without reboot". Then the protection will be enabled the next time you start the computer.



6. After the reboot, the protection service will be enabled, which can be verified by re-entering the section in the configuration window "Services".

As you can see, there are several ways to enable a firewall on a computer running an operating system. Windows systems 7. Of course, you can use any of them, but it is recommended that if the protection was stopped not due to actions in the Service Manager or in the configuration window, you still use other methods of enabling, in particular in the firewall settings section in the Control Panel.
