Community Q&A
- QuestionI did not order Microsoft Defender, how do I delete it?
R2_d2000Top AnswererMicrosoft Defender comes with Windows 10, and, unfortunately, it cannot be deleted. - QuestionIs there a way to turn it off without admin privileges?
Community AnswerNo, you need to be an administrator to disable Windows Defender. This is a security measure to prevent viruses from turning Windows Defender off. However, if you know what you are doing and are certain of the safety of a third party app, it is possible to turn it off by using third party operating systems or startup disks which can access system settings of this system or user account, and disabling services with help of third party apps. - QuestionIt keeps getting switched back to on. Why?R2_d2000Top AnswererThis is because Microsoft Defender automatically turns itself back on whenever Windows restarts.
