Uninstall Windows 10 Defender Antivirus. Disabling via the Registry

Windows Defender is Microsoft's own antivirus, which began to be built into all versions of operating systems starting from 8. Standard system protection works in such a way that, unless you install a third-party antivirus product, it monitors security. But as soon as you download and install another antivirus, the Microsoft tool will turn off automatically and give way to new program. Previously, Windows Defender was criticized, but after the 2016 update it was seriously improved and began to receive more and more positive feedback. Be that as it may, the choice of antivirus is your purely personal matter, so in this article we will take a detailed look at the topic of how to disable Windows 10 Defender permanently or temporarily.

We will talk not only about how to neutralize a standard antivirus, but also give several ways to do this. Naturally, we will also show you how to disable the program for a while so that you can restore the protection later. This may be needed, for example, when installing a game with a crack. We have noticed a situation where Windows Defender tells us that the application is disabled and does not want to work. This problem we'll figure it out too.

After the August 2016 update, the antivirus icon began to appear in the taskbar. The icon can be removed, but the defender himself will continue to work quietly. To do this we do the following:

1. Open the task manager (right click on an empty space on the taskbar).

1. The task manager itself will open. We need to go to the “Startup” section and right-click on the “Windows Defender notification icon” entry, and select “Disable” in the menu that appears.

After this, the icon will disappear from the taskbar and will no longer be displayed. You must restart your computer for the changes to take effect.

You can disable any antivirus, like Windows Defender, only temporarily or for the purpose of replacement. There are situations when we want to establish useful program, but for some reason it is perceived as a virus. It is then that you need to force the defender to change his mind. But in such a situation, the correct thing to do would not be to deactivate the antivirus, but to add the program to the “ White list" We will describe how this is done a little below.

Another option that requires Windows shutdown Defender is its replacement with another antivirus that you download from the Internet yourself. Microsoft has provided for the situation of replacing the security software with a third-party one, and when installing another antivirus, the defender is automatically disabled. Sometimes this does not work and then you have to disable the program manually.

Disable correctly

Let's start disabling Windows Defender. Before doing this, please read the previous section carefully. Deactivating a standard antivirus without installing a new one can lead to the loss of personal data or system crash.

Checking antivirus activity

1. Initially, you need to open the control panel, namely the Security Center section. The easiest way to do this is to search for “tens”. Click on the magnifying glass on the taskbar and enter the word “defender” there, and then select from search results the result we need.

1. If you see a window where the defender notifies us about complete safety PC, which means it is active, and we can proceed to disable it. If, on the contrary, no action is required, then the antivirus is already disabled.

Disable using the program interface

This is the first, simplest and safe way shutdowns standard antivirus. If this option for some reason it doesn’t work, you can move on to more complex and effective solutions, we will describe them below, but for now let’s start disabling Windows 10 Defender through its software interface.

1. Open the defender itself (we described how to do this in the previous section). You can also run Microsoft's antivirus through the system tray. To do this, simply double-click on the program icon.

1. In the window that opens, click on the gear icon - these are the program settings that we need.

1. In the settings window, select the “Virus and threat protection settings” section.

1. Disable the triggers indicated in the screenshot.

The protection will be deactivated, but after a few minutes it will turn on again. This option is suitable only for those users who need to stop the antivirus for a short time. For others, there are more effective instructions.

Disabling antivirus using Group Policy Editor

You can completely disable Windows 10 Defender using a standard tool - the Local Group Policy Editor. First, let's launch it. This can be done through the Run program. Use the keyboard shortcut Win+R.

1. Open the utility and enter the command “gpedit.msc” into the text field without quotes and click “OK”.

1. Open the path indicated in the screenshot in the left pane of the editor and select the “Turn off Windows Defender Antivirus” key on the right side of it.

1. Double-clicking the left mouse button on the selected item will open a new window in which we can disable the defender. Place the checkbox indicator in the “Disabled” position and click “OK”.

After the system restarts, Windows Defender will be disabled.

The Group Policy Editor does not work in Windows 10 Home - in it the operation will have to be performed through the registry.

Disabling via Registry Editor

Let's consider another method that will allow us to deactivate the standard antivirus service. To do this, we need a registry editor, which is present in all versions of Windows.

1. Launch the Run utility using the Win+R hotkeys. Next, enter the command “regedit” without quotes and click “OK”.

1. The Registry Editor will open: we need to follow the path indicated in the screenshot.

1. Now you need to create a new key in the right pane of the editor. To do this, right-click on an empty space and select “New” – “DWORD Value (32 bits).

1. Enter the name of the new key “DisableAntiSpyware” and press “Enter”.

1. Double-click to launch the created entry and set the value to “1”. This will disable Windows Defender. If necessary, it can be activated again by setting the key value to “0”.

Attention! If you already had a key named “DisableAntiSpyware”, just set the value to “1” - you don’t need to create anything.

Ready. The system will notify you that Windows Defender is disabled. The notification area icon will disappear only after you restart the computer.

We use third-party software

If for some reason it was not possible to disable your native antivirus, you can resort to another method - third party programs. There is a huge amount of similar software, but it is better to use a utility we have tested called Win Updates Disabler. In one of the articles we talked about, this program was also used there. You can download the application a little lower, but for now let's figure out how to work with it.

1. Open the program that you have already installed by this time, and check the box next to “Disable Windows Defender” (other items should not be checked).

The program will notify us that the changes made have been applied and in order for them to take effect, you need to restart the computer. We agree and click “OK”.

You can also use another, more functional program, Destroy Windows 10 Spying or DWS, which you can also download on this page. The application was created to disable spyware functions in Windows, but it also has the function we need - deactivating the defender. Let's look at how this is done.

1. Download the program and run it (no installation required). Go to the “Settings” tab, check the box next to “Enable Professional Mode” and “Disable Windows Defender”.

1. Now you need to apply the changes. Go to the “Home” section and click on the button indicated in the screenshot.

1. After pressing the key, Windows Defender will turn off and we will be prompted to restart the PC. We do this by first saving all the data and closing the programs.

Attention! When working with DWS, not only the standard antivirus is disabled. Please take a look at the screenshot before applying the changes.

Using PowerShell

There is another way to deactivate the built-in defender. To do this you need to run command line or PowerShell. The choice of environment depends only on you, but in both cases the tool must be called exclusively as an administrator. Let's get started.

1. Let's use the search in the taskbar again. Click on the magnifying glass icon, enter the phrase “PowerShell” in the search field and right-click on the result, selecting “Run as administrator”.

1. When the shell opens, paste the command “Set-MpPreference -DisableRealtimeMonitoring $true” into it without the quotes and press Enter. The system will think for a moment and go back to standby mode. This indicates the success of the operation. All that remains is to close the window and reboot the system.

The same can be done through the command line. Don't forget to run it as administrator.

Disable unprotected notification

The protection is disabled, but now another problem has appeared: constant notifications that our computer is no longer protected and is at risk. This is for security purposes, but if you disable your antivirus deliberately, you should know what you are doing.

Let's turn off notifications that only interfere with your work.

1. Using standard search tool Windows 10 find and open the Security Center.

1. As you can see, the standard antivirus is already disabled.

1. Click on the gear icon and go to Windows Security Center settings.

1. Switch the trigger and turn off notifications - it's simple. You can also remove messages from the firewall right away.

Adding an app to Windows 10 Defender whitelist

There is no need to disable your antivirus. You can simply add the program that he “scolds” to the so-called trusted zone or white list. We will consider an example of adding a file or folder to trusted ones using the example of Windows 10 Pro 64 bit Defender. Let's get started.

1. We open our antivirus by clicking on its icon in the system tray (the program can also be launched through the search, using the method described above). Click on the gear icon and go to the program settings.

1. Click on “Virus and threat protection settings.”

1. Scroll the window to the “Add or remove exceptions” item and click on it.

1. Click on the inscription “Add exception” and in the drop-down menu select the object that interests us.

The following options are available:

• file. Allows you to add specific file in a single quantity, for example, .exe;
• folder. Allows you to add an entire directory to exceptions. It may be necessary when there are too many objects and adding them one by one is inconvenient;
• file type. Adds a file extension and excludes all objects with that extension from the scanning area;
• process. You can enter the name of a process that you don't want the defender to pay attention to.

Let's add to quarantine using a directory as an example. Click on the plus sign and select “Folder”. In the window that opens, left-click on the desired directory and press the “Select folder” button.

The folder has been added to antivirus exclusions. Now it will not scan it and look for viruses. From here you can delete the object and force the program to scan it again.

Let's sum it up

Many users ask the question: how to remove Windows Defender? This cannot be done, but we have learned how to disable it in several ways at once. It is important to understand the danger that our computer is exposed to without an antivirus installed on it. software. You need to deactivate protection only for the purpose of replacing it as quickly as possible or for a short-term installation session of a program that the defender perceives as a virus.
