Windows Defender is a free program that helps protect our computers against pop-ups, slow performance, and security threats caused by spyware and other unwanted software. Actually, it is installed with Windows when you install your operating system. But if you have already running a full anti-malware suite, you can also disable it in case it wastes precious resources of your computers.
Note: Frankly, Since Windows Defender is entirely built into Windows, you can’t uninstall it. The only thing that we can do is disable it.
How to Disable Windows Defender
To open up Windows Defender, go to Tools on the top menu, and then click on “Options”.
In the new screen, click on “Administrator” on the left-hand pane, then uncheck the box for “Use this program”, and click the “Save” button.
Then a message pops up by saying that the program is turned off.
Of course, if you want to confirm if it is turned off, you can also open up the Services panel through Control Panel (or by typing services.msc into the Start Menu search or run boxes). Find Windows Defender in the list and double-click on it.
Note: I’m not recommend you disable Windows Defender because it can indeed protect our computers. Make sure you keep yourself protected from malware!
