Uninstalling Windows Defender on Windows 10 might seem daunting, but it’s actually a straightforward process. By following a few simple steps, you can disable and uninstall this built-in antivirus program to make way for an alternative security solution. Here’s how to do it.
How to Uninstall Windows Defender Windows 10
In this guide, we’ll walk you through the process of uninstalling Windows Defender from your Windows 10 system. You’ll need to interact with system settings and the registry, so proceed carefully.
Step 1: Open Windows Security Settings
First, click on the Start menu and type "Windows Security" to open the Windows Security settings.
In the Windows Security dashboard, you’ll find various options related to virus and threat protection, firewall, and more. This is where you can manage the built-in security features of Windows Defender.
Step 2: Disable Real-Time Protection
Next, navigate to "Virus & threat protection" and then "Manage settings." Turn off the toggle for real-time protection to disable Windows Defender temporarily.
Disabling real-time protection will stop Windows Defender from actively scanning your system, allowing you to proceed with the uninstallation process.
Step 3: Open Registry Editor

The Registry Editor is a powerful tool that lets you modify system settings. Be cautious when making changes here, as incorrect edits can affect your system’s stability.

In the Registry Editor, go to HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows Defender. Right-click on the "Windows Defender" folder and select "New > DWORD (32-bit) Value."
Name this new value "DisableAntiSpyware" and set its data to 1.
Step 5: Restart Your Computer
After making these changes, restart your computer to apply the new settings.
Restarting your system will complete the uninstallation process, ensuring that Windows Defender is no longer running in the background.
Once you’ve completed these steps, Windows Defender will be disabled, allowing you to install an alternative antivirus program of your choice.
