How to Turn Off Defender in Windows 11 & 10 PC

Windows Defender works in the background on Windows 11 & 10. If this feature is on, it will quickly stop you from installing harmful software.

But you might want to stop Defender from acting on its own. You can change this in the settings. On the other hand, you might use a paid, strong antivirus. Then, turning it off will help save memory.

But if you have no other protection on your PC, keeping it on is very helpful. Also, there are two ways to turn off Defender in Microsoft OS 11 or 10 fully.

But sometimes, you may not turn it off forever. The system turns it back on. Therefore, follow the steps below carefully to fix the problem entirely.

How to Turn Off Defender Step by Step

Do you want to remove or disable it from your PC? Then, see the steps below. This way, this antivirus will no longer work on your device. You will have complete control.

As a result, you can manage your system’s security settings as you wish.

Step 1

Open the Task Manager. You will see that Windows Defender is using a lot of RAM. This may come as a surprise to you.

Because of that, memory use shows how it protects your system in real-time. So, you are always keeping your system safe from possible dangers.

Step 2

To disable Defender, you must first go to the settings menu. To do this, usually right-click on the taskbar at the bottom of the screen.

Then, from the context menu that you see, click on the “Settings” option. This way, you will open the window. There, you can make the necessary settings to turn it off.

Step 3

In the newly opened window, find the ‘Home’ tab at the top. Then, click on it. In fact, this tab will be your gateway to the main features & settings.

Step 4

To keep going, open the Windows Settings menu and click on “Update & Security.” Here, you can manage system updates and security settings. You can also fix problems to keep your device working well.

Step 5

When you click on Windows Defender, you will see standard settings on the right. To make things better, turn off Real-Time Protection in these options.

Next, turn off Cloud-Based Protection too. This will let you set your security options again from the start.

Advanced Settings and Service Management

Step 1

After you scroll down the window a little, turn off “Automatic sample submission.” Also, if you do not want to get notifications, turn off “Enhanced Notifications.”

Step 2

If you’re working on an older version of Windows 10, you’ll see the image below. But the newer builds have a more modern look. Fortunately, you’ll know that you’ve disabled Defender software. This is true no matter what your system is.

Step 3

To open the services management console, first press Windows Key + R. In the Run toolbox that opens, type the command “services.msc” & hit Enter.

So, you will open the Services window. There, you can see and manage system operations on your computer.

You control different system services in the Services window. Let’s take a step further. You can turn on the SNMP service right here too.

Step 4

First, scroll down to find the Windows Defender entry in the Services window. Then, double-click it here to open its properties window. However, don’t worry if you can’t interact with the options. In that case, move on to the next step to continue.
