In Windows 10, Windows Defender Antivirus is a free and reliable anti-malware feature designed to protect your device and data from unwanted viruses, ransom demands, spyware, and many other forms of malware, and even hackers. While this is sufficient for most users, it is sometimes advisable to disable your virus protection either permanently or temporarily.


For example, if you are not convinced by the solution. You need to perform a specific task that requires you to disable the function of your device. You install a kiosk computer that does not want to connect to the network. Or you need to comply with your company’s security policies.

The only caveat is that Windows 10 does not have an option to uninstall or “permanently” disable Windows Defender antivirus unless you install a third-party antivirus program. However, you can always disable the built-in security feature through the group policy or registry, or even temporarily through the Windows security application.
