GPO Background processing

We have a GPO that sets permissions on certain folders/files. When the policy was updated management wanted to see that change happen on user desktops that the GPO was applying to. Background processing doesn’t appear to apply them. I know that some things don’t change until the machine is rebooted but I can’t get a reading on whether it applies to folder/file permissions.

Also, is there a way you can tell if background processing is working? It doesn’t appear to create an Event Log entry.

Thanks!
