A Group Policy Object (GPO) is a feature in the Microsoft Windows operating system that allows administrators to manage and configure settings for users and computers within an organization. GPOs can control various aspects, such as security settings, software installation, and desktop environments, ensuring consistency across multiple devices. GPOs are linked to Active Directory containers like sites, domains, or organizational units, enabling targeted application of policies. This centralized management helps streamline administrative tasks and enhances security by enforcing specific configurations across the network, making it easier to maintain compliance with organizational standards.
