Summary: Use Windows PowerShell to add an exclusion folder to Windows Defender.

Hey, Scripting Guy! Question How can I add the C:\temp folder to the exclusion list so it is not scanned by Windows Defender?

Hey, Scripting Guy! Answer Use the Add-MpPreference cmdlet and specify the exclusion path, for example:
