  1. Hmmm. Why would anyone want to disable Windows Defender? I think it serves its purpose comfortably. I actually had to stop using 3rd party antivirus apps.

  2. @Kay_Smyles, You might need to disable it when you wish to test another antivirus. Windows Defender is free but not exactly the best out there.
