Disabling Windows Defender in Windows 10 isn’t as tricky as it sounds. With a few simple steps, you can turn off Windows Defender so it doesn’t interfere with other software or your system’s performance. It’s a straightforward process and won’t take more than a few minutes.
Step by Step Tutorial: Disabling Windows Defender in Windows 10
Let’s walk through the steps to disable Windows Defender in Windows 10. These steps will guide you through using the Windows Security app and the Registry Editor to turn off the built-in antivirus software.
Step 1: Open Windows Security
The first step is to open the Windows Security app.
You can do this by searching for "Windows Security" in the Start menu search bar and clicking on the app when it appears. This app is the control center for all security features on your computer.
Step 2: Navigate to Virus & Threat Protection
Next, go to the Virus & Threat Protection section.
Once you’re in Windows Security, look for the "Virus & threat protection" option on the left-hand side. Click on it to open the settings related to your system’s antivirus protection.
Step 3: Manage Settings
Now, click on "Manage settings" under Virus & Threat Protection settings.
This option is usually under the "Virus & threat protection settings" heading. Clicking it will take you to more detailed settings where you can customize how Windows Defender operates.
Step 4: Turn Off Real-Time Protection
Next, toggle the switch to turn off Real-time protection.
You’ll find a switch labeled "Real-time protection." Turning this off will immediately disable the real-time scanning feature of Windows Defender. Don’t worry; you can turn it back on anytime.
Step 5: Access Registry Editor
For a more permanent solution, open the Registry Editor.
Press the Windows key + R to open the Run dialog box, type "regedit," and hit Enter. The Registry Editor is a powerful tool for making deeper changes to your system settings.
Step 6: Navigate to Windows Defender Key
In the Registry Editor, navigate to: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows Defender.
This is where you can make changes that Windows Security can’t override.
Step 7: Create a New DWORD Value
Right-click in the right pane and select New > DWORD (32-bit) Value. Name it "DisableAntiSpyware."
After creating the new DWORD value, double-click it and set the value to 1 to disable Windows Defender permanently.
Step 8: Restart Your Computer
Finally, restart your computer to apply the changes.
Rebooting your system ensures that all the changes take effect and Windows Defender is fully disabled.
Once you’ve completed these steps, Windows Defender will be disabled, allowing you to install other antivirus software or improve system performance without interference.
