Contrary to the popular misconception, Microsoft has been sending a basic anti-spyware since the days of Windows XP. However, after the release of Windows 7, 8 and 10, Microsoft brought a full antivirus, Windows Defender (now called Windows Security) with support for antimalware execution, real-time detection and timely update of definitions. That said, some users do not find the native antivirus effective and others find it too demanding on computer resources. Recently, we wrote about how Windows Defender increases CPU usage abnormally through the msmpeng.exe process. Therefore, if you also face these problems or simply want to install an antivirus of your choice, follow our guide and learn how to disable Windows Defender Antivirus in Windows 10.
Disable Windows Defender Antivirus Using Registry
Here, we will use the Windows Registry tool to disable Windows Defender Antivirus. For this method, make sure you are using the administrator account before continuing. Now, let’s start.
1. First, open Windows Defender or Windows Security and go to “Protection against viruses and threats”. Here, click on “Manage settings”.
2. After that, uncheck all options under “Virus and threat protection settings”.
3. Now, search for “record” in the Windows search box. After that, click on “Run as administrator” in the right panel.
4. Copy the following address and paste it into the Address bar of the Registry and press enter. You will be instantly taken to the Windows Defender folder.
HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows Defender
7. Right-click on “Windows Defender” and select New -> DWORD value (32 bits). Name the file “DisableAntiSpyware” and click on the “OK” button.
8. Now double click on the file and change the value to 1. After that, click on the “OK” button and restart your computer.
9. Finally, open Windows Defender or Windows Security and you will find that the antivirus is completely disabled. Now you can continue and install a third-party antivirus on your Windows 10 PC.
Note: If it does not work in the first try then try for the second time and it will surely work.
10. In case you want to enable Windows Defender again, simply delete the “DisableAntiSpyware” file from Registry and restart your computer. The native Windows antivirus will start working again.
Disable Windows Defender Antivirus Using Group Policy
If the registry trick does not work for you, you can take advantage of the Group Policy Editor to disable Windows Defender permanently. However, keep in mind that Group Policy Editor is only available in the administrator account and on PCs running Windows 10 Pro version. Then, with all that said, let’s start.
1. Press the “Windows” and “R” keys at the same time to open the Run dialog box. Now, type “gpedit.msc” in the search box and press enter to open the Group Policy Editor.
2. Here, expand the “Administrative Templates” menu in the “Computer Configuration” section.
3. Next, expand the “Windows Components” menu and scroll down to “Windows Defender Antivirus.”
4. Here, double-click on “Disable Windows Defender Antivirus” and select “On” in the upper left corner. Subsequently, click on the “Apply” and “OK” button.
5. Finally, restart your computer and this time, you will find that Windows Defender is disabled on your Windows 10 PC.
6. If you want to enable it again, simply open the Group Policy Editor again and select “Not configured”. That’s.
Remove Windows Defender Antivirus from Windows 10
These are the two ways you can remove Windows Defender Antivirus from your Windows 10 PC. While the registry trick works most of the time, Microsoft sometimes reverses the change after an update. So, if you are facing such a problem, choose the most powerful group policy editor that controls the behavior of all system applications in Windows 10 Pro. Apart from that, the oldest way to disable Windows Defender using the Windows services no longer works, so I haven’t mentioned that method. Anyway, that’s all of us.
