Reversion Mode
The second set of options on an element dictates the reversion mode, or the policy removal options.
These actions apply when the group policy object (GPO) is no longer relevant to the user, such as when the GPO is deleted, the value is deselected, the user is moved out of the GPO, or a Windows Management Instrumentation (WMI) filter on the GPO evaluates to false. The term for this is "falling out of scope."
There is only one available reversion mode: "Revert this policy setting to the default value when it is no longer applied." When the GPO falls out of scope, the original application value (as defined within the AppSet) is enforced on the application.
The default is to have the "at least one symbol character (!,@,#,$,%,^,&,*…)" checkbox unchecked, which means that the value will be retained on the client—even though the GPO falls out of scope.
Note that when the reversion mode is set, the text in the Endpoint Policy Manager Application Settings Manager user interface changes to italics as a visual signal, as seen in Figure 27.
