How to disable Windows defender? I have McAfee installed

Hi Boyd,

Windows Defender is a built-in security program included in Windows 10, therefore, it cannot be uninstalled. However, if it detects a different anti-virus installed or running on your device, it will automatically disable itself from running.

Real-time protection should be turned off automatically. Defender is not completely disabled any longer to allow manual scanning.

Yes this helped. Thanks for your feedback. Typically other programs have to be uninstalled to avoid conflicts.
