Managing Windows Group Policy is complex enough without having to manually open ADMX and ADML files to find out which registry key a policy controls. This tool gives you direct access to that information.

Browse and search ADMX administrative templates to quickly identify the registry path, value name, data type, and possible values for any Group Policy setting. No need to open Group Policy Editor, no need to manually parse ADMX or ADML files.

Why this tool exists

Finding the registry key associated with a Group Policy setting typically involves manually opening ADMX and ADML files and searching through hundreds of lines. This tool makes that process straightforward. Search by policy name or registry key to get the information you need without manual work.

Who is this for

This tool is built for system administrators and endpoint engineers working with Group Policy or MDM solutions. Whether you are deploying Group Policy settings, troubleshooting whether a GPO is correctly applied, or documenting policy configurations for compliance, knowing the exact registry path behind a setting is essential.

What you can do here

Browse ADMX files from Microsoft and third-party vendors, search by policy name or registry key, view the full registry path (HKLM or HKCU) for each setting, see enabled and disabled values with supported data types, and share direct links to specific policies with your team.

Troubleshooting GPO application

When a Group Policy is not behaving as expected, checking whether the correct registry key is being set or modified confirms whether the GPO is actually applied. Instead of manually searching through ADMX and ADML files, look up the expected registry path here and verify it directly in the Registry Editor.

Missing an ADMX file?

The library is continuously growing, but not every vendor template is included yet. If you are working with an ADMX file that is not listed, send it to [email protected]. It will be reviewed and added to the collection so others can benefit from it as well. Contributions from the community keep this resource useful for everyone.
