However, the updating of Group Policy depends upon the resources that have been modified and may vary according to the priority. Even when you change Group Policy Refresh Interval and set it at 0 minutes, the computer tries to update Group Policy every 7 seconds. Generally, by default Group Policy gets updated in the background every 90 minutes, after a change is recorded in the active object. Group Policy helps users to add policies for active objects by making modifications in Windows Windows Registry. Group Policy, an administrative tool introduced in Windows 2000, determines how programs, network resources, and operating systems behave for users and computers in an organization.
