| Description | ||||
| Disabled (Default): If this setting is not configured or disabled, local admins can see exclusions in the Windows Security App or via PowerShell. Enabled: If this setting is enabled, local admins no longer see the exclusion list in Windows Security App or via PowerShell. Note: Applying this setting will not remove exclusions, it only prevents them from being visible to local admins. This is reflected in Get-MpPreference. | ||||
