How to enable Windows Defender and what it is

Windows defender is a built.in program that helps to avoid the appearance and damage of viruses. Users are debatable for it: the utility has both a number of advantages and a number of minuses. Often she stops working, and for a variety of reasons. Therefore, it is important to understand how to enable Windows Defender.

This program was originally present in the latest operating system. As updated, it was improved and was called “Security Windows”. The functionality of the firewall has expanded significantly. The utility supports security with:

  • warnings about the presence or manifestation of malicious software;
  • scanning of several types followed by removal of dangerous applications;
  • schedules set by the user.

Despite all the advantages, many people still refuse the defender in favor of other antiviruses. Usually they substantiate it with its too low efficiency. In addition, quite often there is such a problem as turning off the program. One of the most common reasons for this is to update the OS.

Why manually disconnect the program

According to Windows Defender statistics, it has unenviable performance and, most importantly, does not notice a significant part of the malicious. However, the utility conflicts with any other antiviruses, but you can’t just remove it. Therefore, the owners of the new operating system are forced to use many ways to completely disconnect the program.

How to configure Windows Defender

The utility is made so that the user spends a minimum of time on it. The defender works automatically, and therefore human intervention is usually not required. You can configure the program in parameters (open with a combination of Wini). Most often this is used to add exceptions to the defender.

How to enable “defender” in Windows 10

There are several methods to enable the program. Depending on the cause of the problem, version and editorial office of the OS, some of them may be useless. It should also be noted that all of the listed options are quite simple so that even an inexperienced computer owner copes with them.

Options

You can open the desired window in two ways. First and fastest: find “Windows safety” in the “Start” menu. The second is to open it directly through the parameters themselves.

To enable the defender, you must first open it. Once in the corresponding section, you need to click on the following button:

Next, a window will appear where it will be possible to activate protection against malicious software. It is important to consider that in some cases the service only after several presses on the power button.

Registry editor

You need to press Winr, and then write in the only line “Regedit”. Next, it is required to find the section responsible for the firewall. It is located the following path:

Having twice clicking on the LKM on the point on the right side of the window (circled in the screenshot), you should put in the field “Value”. Also, if necessary, the procedure must be repeated in the parameter responsible for protection in real time. Upon completion, it is recommended to restart PC.

Group policy editor

It is important to immediately pay attention to the fact that this method is not suitable for the editors of Home. First you should open the “Perform” window by pressing the combination of the Winr keys. The team calling this editor is GPEDIT.MSC. Antivirus is at the following address:

In the specified folder among the parameters, you can easily notice a item that allows you to turn off the defender (it is located almost immediately after folders). To open the settings, you need to press the parameter twice. Next, a large window will appear, in which you need to select “disabled” in the upper left corner.

Utilities

Highlight many programs that make it possible to disable updates, intrusive notifications, etc. D. Including they can affect the firewall. To enable it, you can use Win Updates Disabler. This popular program is easy to master and does not require large time costs, unlike a couple of previous ways. However, it is important to download it only with proven sources, otherwise there is a risk of infection with viruses.

The utility is completely in Russian. There are several points in the window that opened, next to which you can put or remove the checkmarks.

It should be noted that sometimes after turning on the parameters of the antivirus, they are still displayed incorrectly. In this case, a change in values ​​in the register will help (how to open it, has already been indicated earlier). To do this, go to the address indicated in the screenshot and select the following parameter:

Install values ​​2 in the line, and then restart the device.

Windows Defender is a useful utility, but in some cases it may be ineffective. If the defender does not work, it is recommended to start with the simplest way, namely, turn it on through security parameters.

Local group policy editor

If you did not disconnect Windows Defender yourself, then when trying to start the built.in Windows antivirus, you can see such a window with the message that the application is turned off in group policy. Most likely you previously used the special shutdown program.

  • We go to the “Local Group Policy Editor”. for this, click on the keys and R and “Enter” the command: GPEDIT.MSC. The editor can also be launched through the search line in the lower left corner of the system. simple enter the name of the service in the line and start.
  • On the left we find the main section “Computer Configuration”, then go to the “Administrative Templates” folder, we find “Windows” components there and go to the “Antivirus Program Defender Windows” (in the old versions of the Windu can be called “Endpoint Protection”). There will be a parameter that begins with the word “turn off”. go into it with a double click of the left mouse button.

After that, again, we start the native antivirus in the standard way. If this method did not help, then remember whether you previously used the OO Shutup10 program. this is a popular application that allows you to disable the defender. Try to turn on the antivirus through it.

Registry editor

To go there, we use our favorite keys and R and command: Regedit. Or you can enter the words “registry editor” into the search line. Further on the left there will be folders of various sections, you need to walk along the way:

  • We move to the main folder “Hkey_local_machine”.
  • Next, go to Software and find Policies there there
  • Here is the Microsoft subsection and the Windows Defender folder will be we right.

The parameter indicated in the picture below must be installed in zero mode (0). that is, deactivate the superstructure. If the “Disableantispyware” parameter is not, then create it. click PKM on an empty field and create the “Reg_Dword” parameter with a zero value (0). Calculation system, select any.

Expand the Windows Defender folder and find the Real-Time Protection subsection-see if there is a Disablerealtimemonitorin parameter there. If this parameter is, then also turn it off by setting the value 0.

The main way

In fact, I don’t see anything complicated here, so if there are any questions, I propose to safely write them in the Комментарии и мнения владельцев under this article. The only difficulty-in Windows 11, intenses have changed a bit, and this can slightly disorient someone. I show how to find him here.

  • “Privacy and protection. Windows safety” (or you could just in search of Windows 11 immediately enter “Windows safety” and go to the desired section).
open, windows, defender, does, turn
  • Immediately check all the points here. ideally, for a simple user, green checkmarks should be put everywhere everywhere. We need the item “Protection against viruses and threats”.
  • Choose “Parameters Management” and convert everything to the “inclusive” mode (real.time protection switches and cloud protection should be active). We rejoice on the protection included. So if you are looking for a way to open the Windows 11 defender. we are looking for it only, here at any time you can start checking.

Note! If you have a third.party antivirus, Windows Defender will most likely be disconnected, and this is normal. And in the settings of this section you will see something like it (you can not touch anything, although there are “parameters of the Microsoft Defender antivirus program below, where it can be additionally turned on and configured):

If you turn off the group policy

Group policy is available only for Windows 11 Pro. You can read about its inclusion on Windows 11 Home here.

Some will not be able to turn on the built.in antivirus due to the disconnection of group policies:

Computer configuration. administrative templates. Windows components. Windows safety. protection against viruses and threats

Problems and difficulties with the defender

Some users could face the fact that they cannot run it, since the switches are inactive (as in a screenshot).

Sometimes this situation may be accompanied by the “Windows defender is turned off by group policy” how to turn it on if you have a home version of the system and its presence is not implied? We will analyze several possible solutions for this error.

How to include through group policies

If you use a Pro or corporate version of the system, there is a possibility that the built.in antivirus is simply turned off through group policies. Perform these steps to check it:

  • Click Winr and enter MSC to open a group policy editor
  • Pass the “Computer Configuration”. “Administrative Templates”. “Windows components”. “Antivirus program of Windows Defender” (the section was called Endpoint Protection in versions until 1703).
  • Select the parameter “Turn off the antivirus program” and click “Change Policy Parameter “
  • In the window, select the item “Not set” or “disconnected”. If the item is active “inclusive”. The defender will not work.

How to turn on through the register

Some software for disconnecting telemetry Microsoft can at the same time turn off the built.in antivirus. The register creates a value with the Disableantispyware parameter, which interferes with the correct operation of the service. Even when the Windows 10 defender service is not launched, how to turn it on you can find out later.

To start the program, follow the following steps:

Reg Add “Hklm \ Software \ Policies \ Microsoft \ Windows Defender” /V Disableantispyware /T Reg_Dword /D 0

Defender on senior versions of Windows

Defender is available not only for Windows 10, it was present in past versions. In Windows 7 and 8.1 He had such rich functionality as in the 10th version of the system. Next, consider the launch of separateness on each system.

Follow further steps if you want to find out how to enable Windows 7 Defender:

Everything is quite simple, but do not forget about the presence of third.party antiviruses. they can interfere or turn off Defender.

Is Windows Defender good enough?

As for the possibilities of cybersecurity, Windows defender has come a long way from the moment of its creation. It used to be terrible, but recently Microsoft improved Defender to such an extent that it is a fairly good free antivirus.

Since Defender now unites the sandbox and cloud detection of malicious programs, it provides better general safety, and also reveals threats faster than ever before.

Detection of malware, blocking exploits and network attacks, as well as a mark of phishing websites-this is all that Microsoft’s defender is capable of.

In addition, it provides simple monitoring of PC performance and performance, as well as parental control, which includes content filtering, restrictions on the use and tracking of location.

Since the Windows defender now includes all these useful capabilities, users are wondering if they can only rely on it to protect their computers or they will need to use a third.party antivirus program in addition to it.

The fact is that Microsoft Defender is now more closely close to becoming competitive with third-party online security packages. However, this is still unsatisfactory.

Of course, Defender can be downloaded for free, but there is a reason why Internet security packages are so expensive, and not least due to the fact that Microsoft is not engaged in cybersecurity.

Let us know in the comment section below, which solution works best for you, and also what antivirus software you prefer.
