Until recently Windows Defender would automatically disable, if you ran a purchased Antivirus (or one of the many free ones)
However this is not the case anymore, or at least it hasn’t been for me. All of a sudden I’d have both NOD32 and Windows Defender running at the same time.
Since I know double antivirus isn’t equal to double the protection, and since I know NOD32 handles most tests much better than Windows Defender, I’d like to disable Windows Defender entirely.
In Windows 10 this is no longer an easy option – because Windows will automatically re-enable Windows Defender after having disabled it for a while.
However if you’re using Windows 10 Pro, there’s another option: Group Policies. There’s luckily a Group Policy for entirely disabling Windows Defender, and it’s aptly named “Turn off Windows Defender”.
There are no side effects of this, and no automatic re-enabling. So here’s how to do it:
- Hold the Windows key on your keyboard and press R, this will open the Run window.
- Enter gpedit.msc and press OK, this will open the Group Policy window. (You’ll probably be asked whether you’re sure you want to open it by the UAC system)
- Navigate to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Windows Defender.
- In here you’ll find Turn off Windows Defender, double click it to edit it.
- Set it to Enabled instead of Not configured and press OK. This will immediately shutdown Windows Defender, and prevent it from running ever again.
Hope this helps you guys – it sure helped me 🙂
