Where to find Windows Defender. What is windows built-in defender? How to enable, disable and configure it? What to do if Windows Defender won't turn on

Microsoft developers have built into the operating system Windows Defender 7, which is designed to provide reliable protection against virus attacks and malware, while experts state the fact that it is not reliable enough. As a result, third-party antivirus software is installed on almost all computers, and accordingly they try to disable this tool so that it does not take up space in random access memory... Although sometimes the situation develops in such a way that this service, on the contrary, needs to be activated, for example, in a situation when the user does not have enough funds to renew the license of other antivirus programs and they need at least some kind of system protection.

After that, the downloaded file must be run. The interface here is quite simple and contains only one button "Uninstall Windows Defender", for which this program is actually needed.

This application can work as in 32-bit version operating systemand 64-bit.

Note: it is better not to perform this action, but use one of the above two methods to disable the built-in antivirus software. The fact is that if the user wants to activate it back, then when performing the third option, it will be much more difficult to do it. It takes up very little physical space, and in fact, this is the difference between disconnecting and deleting. At the same time, in order to avoid conflicts with other antivirus programs and free up space in RAM, shutdown is quite enough.

How to enable Windows Defender 7

These actions are actually the same as the above shutdown methods. The only thing is that when performing the last steps, in the first method, on the contrary, put a tick on the "Use this program" item, and in the second, in the "Startup type" field, use the pop-up menu to set the "Enabled" option.

If this is a built-in anti-virus software was completely removed from the system, then a reinstallation is required here. At the same time, it is worth considering the fact that instead of Microsoft Defender, Microsoft offers to install Microsoft Security Essentials... Essentially, these malware tracking apps are identical in software. functionality and they differ only in name. In order to download it, go to the official website of the developers, select desired language interface and click on the "Download" button. After that, you just need to run the installation package and install this application in standard mode, there should be no difficulties here.

Very often, users are interested in how to disable the standard antivirus in the new OS from Microsoft "Ten". But over time, this tendency weakens and people, on the contrary, begin to ask about its inclusion. Today we will just talk about how to start Windows 10 Defender if it is disabled and does not want to open. It is impossible to uninstall, as well as reinstall, our application, so you need to restore it.

A regular defender can be disabled for various reasons. For example, another antivirus or if error 557 occurs. The methods given in the article will solve the problem, regardless of its origin.

Turn on Windows 10 Defender

So, let's look at several options for activating Windows 10 Defender when it does not turn on. Try to apply them in order until your antivirus works. Attention! Follow our instructions carefully, checking your actions with the screenshots.

We use standard OS tools

Initially, we will use the tools that are present in the operating system by default. If their capabilities are not enough, let's move on to third-party software.

In system settings

Let's start from the very easy way... You can enable and disable the full-time defender in Windows 10 in the system parameters. Perhaps you are in luck, and this is exactly the situation. For windows activation Defender do this:

Open the menu, whose name is Start, and click on the gear icon.

In the settings search bar, write the defender and select the marked option from the search results.

Click on the "Open Windows Defender Security Center" button.

Here we just turn on the native antivirus program.

If after activation you still see the alarm icon, go to the utility settings by clicking on the gear indicated below.

Next, click on the item marked in the screenshot below.

We activate all triggers that will be disabled.

That's all. The defender should turn on and start monitoring your OS. If something doesn't work out and your computer's security is at risk, try the methods described below.

Using the Local Group Policy Editor

Windows 10 has another interesting and useful tool that is capable of making changes to the OS configuration. This is the local group policy editor. This method will help especially when you encounter the error "this application is disabled by group policy".

Step-by-step instruction:

First, you need to run the utility. The easiest way to do this is through a small program called Run by Microsoft's OS. We use a combination of "hot" keys Win + R. In the window that appears, write gpedit.msc and click OK.

We follow the path (left side half of the program window) Computer configuration— Administrative Templates— Windows components — Windows Defender Antivirus... Open the marked key by double-clicking the left mouse button.

Switch the trigger to the Disabled position and click OK.

That's all, you can proceed to checking the performance of our antivirus.

Attention: in order for the changes to apply, you must restart your Windows 10 computer or laptop.

Using the registry editor

Who among you have not heard of the notorious registry editor. For many, this is a terrible taboo and it is like to climb into the death program ... But no, in fact it is real waythat will help us. For example, in our case it will be the inclusion of the defender.

Using the Run utility launches the registry. To do this, press Win + R, enter the regedit command and click OK.

We go along the way Computer \\ HKEY_LOCAL_MACHINE \\ SOFTWARE \\ Policies \\ Microsoft \\ Windows Defender double-click the left mouse button to open the key marked with number 2.

Set the value to 0 and press the button called OK.

In the same way as in the case of the local group editor, the policy needs to restart the PC to enable the program.

Important: to work with system registry you will need administrator privileges. Otherwise, the editor program simply cannot access the necessary entries, and you will see the inscription: "Some parameters are managed by your organization."

Windows Defender Service

If none of the above options work, try checking if the service you want is running. It is its inactivity that prevents you from protecting your PC. Sometimes the system displays the error "Threat Service has stopped, restart it." To fix this and configure protection, we do this:

Using the combination of buttons Win + R, you need to go into the Run utility, enter the command into it and click on OK.

In the list of processes, you need to find the service of our antivirus and check if it works. If not, open the entry by double clicking on the right mouse button and enable the task.

Note: an icon that appears on the taskbar indicates a running application.

We use third-party software

There are many programs that can help with this issue. There is no point in describing their duplicate functionality, so let's talk about the two best and dissolute representatives.

Win Updates Disabler

You can download the program for free on its official website. When it's done, run the setup file.

Check the box for agreeing to the terms of the license and click Next.

Skip the installation information and move on to the next step.

If necessary, you can change the installation path here. In our case, this is not required, so click Next.

We set a shortcut in the Start menu or leave everything as it is.

Beginning with the Seven, Microsoft began to provide its operating systems with a built-in utility to protect the computer from viruses and called it "Windows Defender". And we must pay tribute to this innovation, since in Windows 10 this defender can cope well and protect Windows from most of the negative consequences of malware infection, but only if its databases are regularly updated. However, in our country it has historically developed that a significant number of users work in pirated operating systems and therefore are forced to disable the Windows update service.

It is obvious that after that the Windows Defender anti-virus database, updated through packages windows updates 10, as a rule, is no longer relevant. Thus, it is not recommended for owners of official OS versions to disable this built-in protection in Windows 10. But there are times when even in the licensed Top Ten this antivirus program, which functions by default, creates significant problems for the user, for example, does not allow the installation of an application or a computer toy, prohibits the launch of applications, or uninstalls some program files.
