Group Policy Objects (GPOs) are a feature of the Microsoft Windows operating system that allows administrators to manage and configure settings for users and computers within a Windows domain. GPOs can control various aspects, such as security settings, software installation, and desktop environments, ensuring consistency across an organization. GPOs are applied at different levels, including site, domain, and organizational units (OUs). This hierarchical structure allows for flexible management, where specific policies can be tailored to different groups or departments. By using GPOs, organizations can enhance security and streamline administrative tasks efficiently.
