Windows 10 Defender does not turn off. Turn Windows Defender on and off. Disabling using the Windows Registry

The operating system should not only be as functional and productive as possible, but also well protected. In Windows, such protection is provided by a comprehensive security system, an important part of which is Windows Defender– a built-in anti-virus program from Microsoft, designed for automatic and manual search, detection and removal of virus threats. In addition, built-in Windows 8/10 Defender can monitor and prevent suspicious changes in real time in specific OS segments.

However, the vast majority of users prefer third-party antivirus products to it, and for good reason. Tests conducted by independent laboratories have shown that the protection provided by Windows Defender in both the eighth and tenth versions of the system is very conditional, significantly inferior in many respects to popular antivirus programs. It is not surprising that more and more users are wondering how to disable Windows Defender 10 at least temporarily, and even better permanently.

Disabling Defender via Settings

In theory, when installing third-party antivirus software, Defender should turn off automatically, but you can do this manually. The easiest and most obvious way is to disable Windows 10 Defender through the Settings application settings. So, open Settings, go to Update & Security, switch to the Windows Defender category and turn the Real-time Protection switch to Off.

Be aware, however, that this method cannot in any way be considered reliable, since after some time the system itself will re-enable the protection.

Using the Local Group Policy Editor

But how to disable Windows 10 Defender permanently so that it never turns on again? This is quite possible, only this time you will have to change the settings at a higher level. Team gpedit.msc in the “Run” window, open the local group policy editor and go to the path in the left column Computer Configuration – Administrative Templates – Windows Components – Endpoint Protection.

In the right part of the window, find the “Disable Endpoint Protection” policy, double-click on it and activate the “Enabled” radio button in the window that opens.

After this, Defender will be disabled permanently, and whenever you try to start it in the usual way, the system will generate an error.

Via Registry Editor

Disabling Windows 10 Defender is also possible through the Registry Editor. In this case, the result will be similar to the previous one. Team regedit open the registry editor and expand the branch in the left column HKEY_LOCAL_MACHINE/SOFTWARE/Policies/Microsoft/Windows Defender. On the right side of the editor window, create a new 32-bit DWORD value and name it DisableAntiSpyware and set its value to 1.

If the setting is already present, simply change its value from 0 to 1. Close Registry Editor and restart your computer for the changes to take effect.

Windows 10 Defender Service

In previous versions of the system, the Windows Defender service could be disabled in the Services snap-in. In Windows 10, this cannot be done because the corresponding option is locked for editing, and if you open its properties, you will see that all service controls are grayed out.

Use the methods given above or below to disable the built-in antivirus.

In the Task Scheduler

There is another way to deactivate Windows Defender. We will now show you how to disable it. This time we will use the Task Scheduler. Run it with the command taskschd.msc and go to the left column along the path Task Scheduler Library - Microsoft - Windows - Windows Defender.

In the middle column, find the “Windows Defender Scheduled Scan” task, double-click on it, switch to the “Conditions” tab, check the “Run task when the computer is idle” checkbox and set the value to 1 day.

Alternatively, on the “Action” tab, you can replace the path to the Defender executable file. Just keep in mind that these methods are ineffective.

Third party utilities

We have discussed the main ways to disable Defender using the system, now let's see how to disable Windows 10 Defender using third-party utilities. The most commonly used ones are NoDefender, Win Updates Disabler and Destroy Windows 10 Spying.

NoDefender

The NoDefender utility is the simplest. It does not require installation, and disabling Defender in it is reduced to pressing one “Disable Windows Defender” button. True, using the program has some peculiarities. So, before disabling Defender itself, you need to open its settings in the Settings application and deactivate the Real-time Protection, Cloud Protection, and Automatic Sample Sending functions.


Win Updates Disabler

The Win Updates Disabler utility was originally developed as a means of disabling updates, but it can also disable Defender. The program is distributed in regular and portable versions and supports the Russian language. It is extremely simple to use. Launch it, check the “Disable Windows Defender” checkbox, and click the “Apply Now” button. After making changes, you will need to restart your computer.

Destroy Windows 10 Spying

Destroy Windows 10 Spying works in a similar way. After launching this utility, you will need to switch to the “Settings” tab, enable professional mode and check the “Turn off Windows Defender” checkbox.

The changes will take effect after a reboot.

Complete removal of Windows Defender 10

By and large, that’s all with Defender stopping; all that remains is to answer the question of how to remove Windows 10 Defender forever and whether it can be done. This is possible, but why violate the integrity of the system by forcibly removing a component if you can simply disable it? When disabled, Defender does not consume system resources and certainly does not take up any significant disk space.

If you still really want to get rid of it, follow these steps. Using any of the above utilities, disable Defender, make sure it is also disabled in the Local Group Policy Editor, then go to the C:/Program Files location, unlock (change owner) the Windows Defender folder and delete it and all its contents.

Also you will need to delete the registry key HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows Defender, having previously obtained access rights to it.

If you can’t delete a folder from a running system, boot from any “live” disk with a built-in file manager, for example, Dr. Web LiveDisk. Locate the directory on the disk (most likely it will be in the location /win/e:/Program Files) and force delete it.

Windows Defender or Windows Defender is a built-in tool from Microsoft that is a software solution for managing PC security. Together with a utility such as Windows Firewall, they provide the user with reliable protection against malicious software and make your Internet experience safer.
