How to temporarily disable Windows 10 Defender. Local Group Policy Editor

Windows Defender is a protection against malware, which is included with Windows 10 to protect your device and data from viruses, ransomware, spyware and many other security threats.

Although it is an antivirus that provides strong real-time protection and even automatically disables itself when a third-party solution is detected, it is not possible to permanently disable or remove it completely, as in previous versions.

However, there are still a number of scenarios where you may not be able to use your default antivirus. For example, if you set up a kiosk computer that will not connect to the Internet, no one will be able to connect to peripheral devices. Or when performing certain tasks that would otherwise be blocked by a security feature. If you must disable Windows Defender Antivirus even though your computer is vulnerable to threats, there are several ways to permanently disable the antivirus using Group Policy Editor and the Registry.
