    Thanks for the tip. I will put a shortcut in my WinX Menu. I prefer Defender to any other AV programs out there, and use it in conjunction with Malwarebytes Antimalware Premium.

      To be honest, defender is the first thing i disable after the fresh install.

        It’s actually automatically disabled when you install an antivirus program. If you execute the command in this article while you have an antivirus product installed, you are instead presented with this message (screenshot)
