Video tutorial to disable Windows Defender

1. Disable Windows Defender using Local Group Policy

Windows Defender provides maximum protection when cloud-based protection is enabled. Windows Defender runs in the background and alerts you when you need to take specific action. There are several ways to disable Windows Defender, one of which is by tweaking the Registry.

However, when you want to disable Windows Defender on multiple computers in a domain, the group policy approach is best. If you are using System Center 2012 R2 Configuration Manager and Microsoft Intune, these can provide centralized management of Windows Defender, including:

• Manage settings
• Manage definition updates
• Alerts and alert management
• Reporting and report management

Disable Windows Defender using Group Policy as follows:

Launch the Group Policy Management console. Right-click the domain and click Create a GPO in this domain and link it here. Provide a name for the GPO, and then click OK.

Once the policy is created, right-click on it and click Edit. This will bring up the Group Policy Management Editor . Navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Defender .

Find the "Turn Off Windows Defender" policy setting . Right-click on the policy setting and click Edit.

In the Turn off Windows Defender policy setting , click Enabled. This policy setting disables Windows Defender. Click OK and close the Group Policy Management console.

On the client, we see that the group policy has been applied. When the user tries to open Windows Defender, it will show a box saying “ This application is turned off by group policy”. In case you want to enable Windows Defender, edit the policy and simply change the status of that policy from Enabled to Not Configured or Disabled.

2. Disable Windows Defender using Registry

If you are using Windows 10 Home , you cannot access the Local Group Policy Editor. However, you can still disable Windows Defender using the Registry .

Note:

Before performing the steps below, you should back up the Registry to avoid bad situations.

1. Press the Windows + R key combination to open the Run command window , then type regedit and press Enter (or click OK) to open the Registry.

2. On the Registry window, navigate to the key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

3. If you don't find DWORD DisableAntiSpyware , right-click any empty space, then select New => DWORD (32-bit) Value .

4. Name this new key DisableAntiSpyware .

5. Double click on the new key you just created, set the value in the Value Data box from 0 to 1 .

6. Restart your computer to complete the process.

In case you want to re-enable Windows Defender, you perform the same steps, and in step 5 you set the value in the Value Data frame from 1 to 0 , restart your computer to apply the changes.

3. Temporarily disable Windows Defender using the Settings app

From Windows 10 version 1803 and above , follow these instructions to temporarily disable Windows Defender:

Type Windows Defender Security Center in the search box to open Windows Defender Security Center, click the Settings icon in the lower left corner.

2. On the Settings window, find and click Update & security .

3. Next click on Windows Defender .

4. Switch the Real-time protection option status to OFF .

Depending on your computer usage habits, you can choose the appropriate way to disable Windows Defender.

5. How to turn off Windows Security in Windows 10 (new version)

Note:

Windows Defender AV and the Windows Security app use similarly named services for specific purposes.

The Windows Security application uses the Windows Security Service (SecurityHealthService or Windows Security Health Service), and then uses the Security Center service (wscsvc) to ensure that the application provides the most up-to-date information about the protection status on the endpoint, including protection provided by third-party antivirus products, Windows Defender Firewall , third-party firewalls, and other security measures.

These services do not affect the state of Windows Defender AV. Disabling or modifying these services will not disable Windows Defender AV and result in a lower protection state on the endpoint, even if you are using a third-party antivirus product.

Windows Defender AV will be automatically turned off when a third-party antivirus product is installed and updated.

Disabling the Windows Security Center service will not turn off Windows Defender AV or Windows Defender Firewall.

The downloadable file below will modify the DWORD values ​​in the following registry keys:

(Service Windows Defender Security Center)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SecurityHealthService

(Service Security Center)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wscsvc

DWORD Start

2 = On

4 = Off

B1:  To disable Windows Security for all users, download this Disable_Windows_Defender_Security_Center.reg file .

B2:  Save the .reg file to the desktop.

B3: Double-click the downloaded .reg file to merge.

B4: When prompted, click Run > Yes (UAC) > Yes > OK to approve the merge.

B5: Restart your computer to apply the changes.

B6: Now, you can delete the downloaded .reg file if you want.

6. Turn off Windows Defender by using other antivirus software

Besides the direct methods of disabling Windows Defender (recently renamed Microsoft Defender Antivirus), you can also indirectly disable Windows Defender by installing another antivirus software. This method is quite simple because when you install another antivirus, Windows Defender will automatically stop its activities.

To turn off Windows Defender using other antivirus software, follow these steps:

• Open the website of the antivirus software you want to install. In this article, Quantrimang will try Bitdefender but the instructions for other software are similar.
• Click Download to download the antivirus software installer to your computer.
• Double click on the installer to start the installation process.
• Review and agree to terms of use
• Click Install

After you install the antivirus software, Windows 10's built-in antivirus (Windows Defender) will be disabled. Windows 10 will use the antivirus software you installed as default.

To check, follow these steps:

• Press Windows to open the Start menu
• Search for Windows Security and click on the first result
• Click Settings in the Windows Security window
• Find and click Manage providers under Security providers

• Under Antivirus you will see Microsoft Defender Antivirus is disabled

* Use a third-party antivirus tool instead

If you choose to disable Microsoft Defender, you should install another antivirus program to protect your computer from viruses and malware. Here are some third-party options to consider:

Norton 360 with LifeLock Select ($149.99/year, $99.48 for the first year): While it's been a long-standing name when it comes to antivirus software, Norton Security is still a top-rated option. A subscription to this all-in-one antivirus includes malware and virus protection for your PC and phone, 100GB of cloud backup, a secure VPN, a password manager, and more.

Bitdefender Antivirus (free version available, paid versions starting at $29.99 for the first year): A more affordable option for security software, Bitdefender's free version for Windows PCs offers real-time protection against viruses, malware, and spyware. Paid versions protect more devices and give you a secure VPN.

McAfee Total Protection (starting at $84.99/year, $34.99 for the first year): Another veteran in the cybersecurity world, McAfee continues to score high marks for protection and performance from independent labs. With a paid subscription, you get virus and ransomware protection for unlimited devices (depending on the plan you choose), along with a password manager.

Overall, there are many outstanding antivirus software that are worthy alternatives to Microsoft Defender Antivirus. However, Windows 10's built-in antivirus is still considered one of the best antivirus browsers for Windows 10 users today.

Why disable Windows Defender (Windows Security) on Windows 10?

Typically, this antivirus will block the installation of software from a lesser-known developer because it considers the program suspicious. Anyone who uses legitimate third-party applications will find this annoying. For example, it can be frustrating when custom software that you use for work and that you know poses no threat to your system keeps giving you warnings from your built-in antivirus.

You may have other reasons to disable Windows Defender temporarily or permanently, even though Windows Defender provides one of the best antivirus solutions for Microsoft's operating system. For example, the program may consume too many system resources on a low-end PC.

If your device is not at risk of malware, you can disable Microsoft Defender Antivirus. However, be very cautious before making this decision and always have an additional anti-malware program (one of the suggestions we have given above) available. We strongly recommend that you do so to keep your computer protected.

You may not need Windows Defender because you're using an antivirus solution from another developer. That's okay, because these programs will often perform better than Microsoft's original program.

Some frequently asked questions

1. Is it safe to permanently disable Windows Defender?

The answer is yes. However, you should enable another antivirus program right away. Windows Defender is designed to protect you from the moment you start using Windows, but you don’t have to use it if you don’t want to. That’s why you should leave Windows Defender running until you’re ready to install something else.

Even if you're extremely careful, chances are you'll come across a virus at some point. It's much easier to block viruses than to try to get rid of them.

2. Does Windows Defender make your PC run slower?

Unless you’re running a full system scan, you shouldn’t notice any real noticeable performance impact. In fact, Windows Defender uses fewer system resources than most other antivirus applications. If your PC is running slow, check Task Manager to see what’s running and using the most resources. It could actually be a sign of a virus infection that’s bypassing Windows Defender or another antivirus application you’ve installed.

3. Will installing another antivirus application disable Windows Defender?

This is partly true. Windows Defender can still perform regular scans and will receive regular updates. However, Windows defaults to the antivirus program you choose. For example, when you install Malwarebytes, Windows automatically turns off real-time protection in Windows Defender but keeps regular scans enabled.

If you want to disable Windows Defender, you will need to perform the above options.

4. Is it safe to run Windows Defender with another antivirus application?

Yes. The two programs rarely interfere with each other. Just make sure that they don't both try to run a scan at the same time, as this can affect your PC's performance. Think of Windows Defender as a backup antivirus. However, disabling it won't hurt either. Feel free to use the antivirus of your choice.

Good luck!
