How to disable Windows Defender on Windows 10 Permanently


Windows Defender is a little anti-virus component built into the Windows by Microsoft that comes with every installation of Windows 10.  The security software offers a primary layer of defense to protect your computer against viruses, malware and spyware. It acts more like a shield than a cleaning tool. If you want to install any third-party antivirus program to protect your computer from the virus, you need to disable the Windows Defender. Here, we will provide you some steps to permanently disable Windows Defender from your device using the Group Policy Editor and Registry Editor.
