Group Policy is a feature of the Microsoft Windows NT family of operating systems that controls the working environment of user accounts and computer accounts. Group Policy provides centralized management and configuration of operating systems, applications, and users' settings in an Active Directory environment. By default, Group Policy is updated in the background every 90 minutes, with a random offset of 0 to 30 minutes.
