Disable Windows Defender Service In Windows Server 2008 Or Vista
Disable Windows Defender Service in Windows 1: Click the Start Button and type Services. Click Services once it appears. 2: Scroll down and right-click on Windows Defender, then click Properties. 3: Click the Down Arrow under Startup type: and click Disabled. Then click OK a few times to apply the changes. That’s all there is to it. The next time you reboot your machine, Windows Defender will not start. Looking back, this is what I should have recommended first....
