Windows Defender is the default real-time virus and malware protection that is built into Windows 10. Although the solution is relatively effective, it impacts system performance and many users prefer to turn it off. If you are one of these users, here’s how to do it on Windows 10.
Whether it is to perform certain tasks or to use another antivirus, it can be useful to temporarily or permanently stop Windows Defender. To do this, we will see how to disable Defender Antivirus in Windows 10. It should be noted that this is an anti-spyware solution, the use of a third-party antivirus is therefore recommended.
Temporarily disable Windows Defender
Temporary disabling Windows Defender in Windows 10 can be done simply through the Windows settings menu:
- Access Windows settings by simultaneously pressing the “Windows + I” keys or via the “Start menu” and then click on the settings icon.
- Then select the “Update and Security” option in the settings menu.
- 3. Click “Windows Security” in the column on the left.
- Once in the Windows security menu, select the “Virus and Threat Protection” option.
- In the new window that opens, click on the “Manage settings” option located under “Virus and threat protection settings”.
- Deactivate the “Real-time protection” option using the slider provided for this purpose.
Disable Windows Defender permanently
When installing another antivirus, Windows Defender is automatically and permanently terminated and gives way to the new protection application. Also, the method of adding a key in the registry editor no longer seems to be an effective solution to permanently deactivate Defender. However, there is a little trick to deactivate Defender using the Ultimate Windows Tweaker software, a portable and free tool that allows you to deactivate Defender by force. We still recommend creating a restore point:
- Download and launch the Ultimate Windows Tweaker utility, it is portable and therefore does not need installation.
- In the left bar, select the option “Security & Privacy“.
- Check the “Disable Windows Defender” box then validate by clicking “Apply Tweaks“.
- You will need to restart the PC to permanently apply the changes and disable Windows Defender. If you want to go back and reactivate Windows 10, you will have to relaunch Ultimate Windows Tweaker, go back to the “Security & Privacy” tab then select the “Restore Defaults” option, confirm and restart your PC so that Defender works again.
Finally, note that it is possible to activate Windows Defender again if it has been disabled temporarily or permanently.
