What is a .ADMX file?
The .ADMX file extension stands for a Group Policy Administrative Template File. This type of file is a configuration file used by Windows Group Policy, which is a piece of software technology designed to help manage a group of computers. Inside an ADMX file, you'll find settings that control how user accounts work, how the operating system itself is configured, and how different applications on the computer should behave. These files are really important for people who need to manage a lot of computers at once, like in a school or a large company, because they help make sure every computer is set up the right way without having to change each one by hand.
You can open ADMX files with several programs that are mostly included with the Windows operating system. These programs include the Microsoft Group Policy Object Editor, the Microsoft Group Policy Management Console, and the Microsoft Local Group Policy Editor. Although the Microsoft Windows Server 2003 Resource Kit Tools, which can also open these files, has been discontinued, it was another tool used in the past for this purpose.
ADMX files are powerful because they can control what users can and cannot do on their computers. For example, in a workplace, an ADMX file might be used to stop people from going on the internet or downloading files that could be harmful or not related to work. If you're using Windows 7, you can manage local policies (which are part of what ADMX files control) by using a tool called the Local Group Policy Editor. This tool is part of the operating system and can be found in the Windows\System32 directory under the name gpedit.msc.
Group Policy, the system that uses ADMX files, often works together with Active Directory, which is another system used to manage permissions and access for users and computers within a network. However, Group Policy can also work with other technologies that manage permissions.
If you need to, you can convert ADMX files into a simpler, tab-delimited text format using a tool called the ADM File Parser (AdmX) command-line tool. This tool comes with the Windows Server 2003 Resource Kit Tools package. It's worth noting that ADMX files were first introduced with Windows Vista and Windows Server 2008, so they are a relatively new addition to the Windows operating system.
