Windows Defender (Windows Defender) is a program built into the operating system that allows you to protect your PC from virus attacks by blocking the execution of the latter's code and warning the user about it. This component is automatically disabled when installing third-party anti-virus software. In cases where this does not happen, as well as when blocking "good" programs, manual deactivation may be required. In this article, we'll talk about how to disable antivirus on Windows 8 and other versions of this system.
Before disabling the Defender, you should understand that this should be done only in exceptional cases. For example, if a component prevents installation desired program, then it can be temporarily deactivated and then turned on. How to do this in different editions of "Windows" will be described below. In addition, we will talk about how to enable a component if it is disabled for some reason and there is no way to activate it by usual means.
Windows 10
In order to disable Windows Defender in the top ten, you must first get to it.
There are other options for disabling the application, which are described in the article available at the link below.
Next, let's figure out how to enable the program. Under normal conditions, the Defender is activated simply, just move the switch to the position "On"... If this is not done, then the application is activated on its own after a reboot or after some time.
Sometimes when you turn on Windows Defender, some problems appear in the options window. They are expressed in the appearance of a window with a warning that an unexpected error has occurred.
In older versions of "ten" we will see the following message:
There are two ways to deal with these. The first is to use "Local Group Policy Editor"and the second is to change the key values \u200b\u200bin the registry.
Please note that with the next update, some parameters in "Editor" have changed. This is the case for the two articles referenced above. At the time of creating this material, the required policy is located in the folder shown in the screenshot.
Windows 8
The launch of the application in the "eight" is also carried out through the built-in search.
You can reactivate real-time protection by checking the box (see point 3) or by pressing the red button on the tab "Home".
If the Defender was disabled in the block "Administrator" or the system experienced failures, or some factors influenced the change in the application launch parameters, then when we try to launch it from the search, we will see the following error:
In order to restore the functionality of the program, you can resort to two solutions. They are the same as in the "Ten" - setting up local group policy and changing one of the keys in the system registry.
Method 1: Local Group Policy
- You can access this snap-in by applying the appropriate command in the menu "Run"... Press the key combination Win + R and write
We press "OK".
- Go to the section "Computer configuration", in it we open the branch "Administrative Templates" and further Windows Components... The folder we need is called Windows Defender.
- The parameter that we will be configuring is called Turn off Windows Defender.
- To go to the properties of the policy, select the desired item and click on the link indicated in the screenshot.
- In the settings window, put the switch in the position "Disabled" and click "Apply".
- Next, launch the Defender in the way indicated above (via search) and enable it using the appropriate button on the tab "Home".
Method 2: Registry Editor
This method will help you activate Defender if your version does not have Windows Local Group Policy Editor... Such problems are quite rare and occur for various reasons. One of them is the forced shutdown of the application by a third-party antivirus or malware.
Windows 7
Open this application in the "seven" you can do the same as in Windows 8 and 10 - through the search.
You can enable protection by placing the checkbox, which we removed in paragraph 4, in place, but there are situations when it is impossible to open the program and configure its parameters. In such cases, we will see the following warning window:
You can also fix the problem by using a local group policy setting or system registry... The steps to be taken are completely identical with Windows 8. There is only one minor difference in the name of the policy in "Editor".
Windows XP
Since at the time of this writing, support for Win XP has been discontinued, the Defender for this OS version is no longer available, as it "arrived" along with the next update. True, you can download this application on third-party sites by entering a search query of the form Windows Defender XP 1.153.1833.0, but this is at your own risk. Such downloads can harm your computer.

The release of Windows 8 brought a built-in antivirus defender to the operating system, which migrated to version 10 of "windows".
It works by default until you decide to install some other antivirus software like Kasperskiy or NOD 32.
They will automatically disable the functionality of the firmware that works with Windows.
Many people are interested in the question of how to disable windows 10 defender manually.
This can be done in three ways:
- for a short period;
- through the registry (forever).
- through the local policy editor (forever).
Why is this needed? The fact is that some games, programs and applications that you plan to install on your computer may be perceived by the system as not very friendly.
The defender sees one of the installation files as potentially dangerous and blocks it.
As a result, the installation breaks off and you have to look for a way out of the situation. Turning on the software is not so difficult, but more on that later.
Disable defender
Local Group Policy
First, press the Win + R combination and write the gpedit.msc command.
We are looking for the coveted Windows Defender folder here (in the release, i.e. the final version of the OS, it can be renamed Defender).
Double click on the highlighted item shown in the screenshot.
For this parameter, you need to switch the radio button (checkbox) to the "Enabled" position if you still intend to disable the defender.
After that, you can exit the settings and make sure that your actions are correct by viewing such a notification.
Changes in the system registry
How to disable windows 10 defender through the registry? To do this, go to the registry editor itself. Press the key combination Win + R and enter the regedit command.
There will be a folder with an active defender, which you need to get rid of by making it inactive.
Create a DWORD parameter called DisableAntiSpyware, but only if the component was previously absent in the section.
Advice! If you want to disable the defender, set the value to "0". To reactivate the software, apply "1".
Now, if the antivirus program bothers you, it will only be with rare notifications that it is inoperative and unable to protect the system from malware.
Reactivating Windows Defender
So, you set out to turn on your defender, or you don't know what to do when you see such an inscription.
It occurs in two cases:
- The defender does not work because a third-party antivirus is installed on the PC. In such cases, you should not take any action - the Windows built-in software turned off automatically after installing the security software.
- You yourself managed to deactivate the program, or there was some kind of failure in the system that needs to be eliminated.
In Windows 10, you just need to click on the message that appears in the notification area. Further, the system will bring everything to a proper state.
If you have been playing with the local group policy or registry settings, you will have to restore everything yourself, since the system will not be able to start Windows Defender on its own.
You need to go to again system settings and activate a previously inactive service.
Advice! You shouldn't remove the built-in Windows Defender just because you feel like it. Firstly, it is an antivirus, albeit imperfect. It prevents various malicious software, which is found in abundance on the Internet, from entering the system. It is worth deactivating it only when it is really necessary and you control the whole process.
To be sure of your own safety, we advise you to pre-purchase or download a third-party anti-virus softwaredesigned specifically to provide maximum real-time device protection.
Which antivirus to choose is up to you, but leaving the machine without proper protection is strongly discouraged.
