When you delete a policy, all assignments of the policy to devices and users are removed.
In ZENworks Control Center, click the Policies tab.
Select the check box next to the policy (or policies) that you want to delete.
Click Delete.
If the policy is assigned as a Zone policy, deleting it from the Policies list does not remove it from the Zone policies list. To remove it as a Zone policy, you must also delete it from the Zone policies list. For information, see Removing Policy Assignments From the Management Zone.
