What is a .adm file?

File Extension Details

An ADM file is a Group Policy Administrative Template used by Microsoft Windows operating systems to define registry-based policy settings. These files contain configuration instructions that dictate how the Group Policy Object (GPO) Editor displays policy settings in the user interface and how those settings are applied to the Windows Registry. ADM files are written in a proprietary, plain-text markup language. System administrators use them to manage and enforce system configurations, security policies, and software behavior across a network of Windows computers. While widely used in older versions of Windows (such as Windows XP and Windows Server 2003), the ADM format has been largely superseded by the XML-based ADMX and ADML formats in newer versions of Windows (Windows Vista and later). However, legacy ADM files are still supported for backward compatibility and can be imported into modern Group Policy management consoles.
