Disabling Windows Defender in Windows 10 permanently can be done through the Registry Editor or Group Policy Editor. The steps involve accessing these tools to change settings that will turn off Windows Defender. It’s crucial to follow the instructions carefully to avoid issues with your computer’s security.
How to Disable Windows Defender in Windows 10 Permanently
Disabling Windows Defender will stop the built-in antivirus software from running, which can be useful if you prefer using different antivirus software.
Step 1: Open the Start Menu
To begin with, open the Start Menu by clicking on the Windows icon.
Once you’ve opened the Start Menu, type "Regedit" in the search bar. This will help you locate the Registry Editor, which is essential for making the necessary changes to disable Windows Defender.
Step 2: Search for ‘Regedit’
Next, type "Regedit" in the search bar and hit Enter.
A window should pop up asking for permission to make changes to your device. Click "Yes" to proceed. The Registry Editor will then open, allowing you to make system-level changes.
Step 3: Navigate to the Windows Defender Key
Locate the following path: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows Defender.
You need to drill down through the folders in the Registry Editor to find this path. It’s like navigating through a series of nested folders, so take your time and ensure you’re in the right spot.
Step 4: Create a New DWORD Value
Right-click in the right pane, select New > DWORD (32-bit) Value, and name it "DisableAntiSpyware."
After naming the new DWORD value, double-click on it to open a dialog box. Set the value data to "1" and click OK. This action will disable Windows Defender.
Step 5: Restart Your Computer
Finally, restart your computer to apply the changes.
Your computer needs to reboot to make sure the changes take effect. Once it restarts, Windows Defender should be disabled permanently.
After you complete these steps, Windows Defender will no longer run on your computer. You should see a significant change in how your system operates, mainly if you install a third-party antivirus program.
