How to Uninstall Windows Defender?
It is not recommended to stop the Windows Defender service from starting automatically when you start your PC, and or to completely uninstall Windows Defender.
If you turn off Windows Defender or it gets automatically disabled when you install a third-party app, it doesn’t use so many system resources, so there is no need to stop the service. For Windows 10, you can disable the real-time protection, but keep using Defender for manual scanning as a backup antivirus app. If you are planning to uninstall it, Windows update will restore Windows Defender anyway. Also, Defender takes up very little disk space and there is no need to uninstall it to free up disk space on Windows.
