 ### -Confirm
-The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
-
-- Destructive cmdlets (for example, Remove-\* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: `-Confirm:$false`.
-- Most other cmdlets (for example, New-\* and Set-\* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
+The Confirm switch doesn't work on this cmdlet.
