Group Policy Management Console (GPMC)
Group Policy Management Console (GPMC) is a scriptable Microsoft Management Console (MMC) snap-in, providing a single administrative tool for managing Group Policy across the enterprise. Originally, GPMC was provided as a separate download component for Microsoft Windows® XP and Windows Server 2003. In Windows Vista with no service packs installed, it is integrated directly into the operating system and is the standard tool for managing Group Policy. The Local Group Policy Editor is provided for managing local policy settings.
GPMC now takes advantage of capabilities provided by newly developed XML-based, resource-independent policy definition files (known as ADMX files). For more information, see New Format and Functionality of Administrative Template Files (ADMX).
