Description

The Remove-MpPreference cmdlet removes exclusions for file name extensions, paths, and processes, or default actions for high, moderate, and low threats. If you attempt to remove an exclusion that is not in the list, this cmdlet reports the error.

Examples

Example 1: Remove a folder from the exclusion list

This command removes the folder C:\Temp from the exclusion list.

Example 2: Exclude a specific file

Remove-MpPreference -AttackSurfaceReductionOnlyExclusions "C:\Windows\App.exe"

This command will exclude only that specific file app.exe in that specific folder.
