Administrative templates enable administrators to control registry settings using Group Policy. Microsoft Windows Vista and Windows Server 2008 introduce a new format for displaying registry-based policy settings. Registry-based policy settings (located under the Administrative Templates category in the Group Policy Object Editor) are defined using a standards-based, XML file format known as ADMX files. These new files replace ADM files, which used their own markup language.
Configuration file used by Windows Group Policy, a software technology used to manage groups of computers; contains settings for user accounts, operating system configurations, and applications; used for storing configurations for the centralized management of many computer systems. ADMX files control what users are capable of doing on their computer. For example, an ADMX file in a work environment may restrict access to the Internet or downloading certain types of files. Windows 7 administrators can access local policies using the Local Group Policy Editor MMC snap-in (.MSC file), which is named gpedit.msc and is located in the \Windows\System32\ directory. Windows Group Policy is often setup with Active Directory, a permissions manager. It can also work with other supporting permissions technologies. ADMX files can be exported to a tab-delimited text file using the ADM File Parser (AdmX) command-line tool. The tool is included with the Windows Server 2003 Resource Kit Tools package.
