Here’s a quick note on a new KB article/hotfix we published for Microsoft System Center Configuration Manager version 1606. The issue you may run into is one where the buttons to create, edit, or delete rules are dimmed and unavailable on the "Specify the rules for a compliant device" page of the Create Compliance Policy Wizard. Additionally, you cannot add a rule with the “Network firewall on” condition to an existing compliance policy. This issue can occur after you upgrade from System Center Configuration Manager version 1602 to version 1606.
If you experience this problem, a hotfix is available for installation in the Updates and Servicing node of the Configuration Manager console for version 1606. For compete details please see the following:
