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.

More Information

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.

NOTE: ADMX files were introduced with Windows Vista and Windows Server 2008.
