The Central Store is a file location that is checked by the [[Group Policy]] tools by default. The Group Policy tools use all [[Administrative Template files (ADMX & ADML)|.admx files]] files that are in the Central Store. The files that are in the Central Store are replicated to all [[Domain Controller]] in the [[Active Directory Domain]]. # Creating a Central Store To create a Central Store for `.admx` and `.adml` files, create a new folder named `PolicyDefinitions` in the following location (for example) on the domain controller: `\\contoso.com\SYSVOL\contoso.com\policies\PolicyDefinitions` When you already have such a folder that has a previously built Central Store, use a new folder describing the current version such as: `\\contoso.com\SYSVOL\contoso.com\policies\PolicyDefinitions-1803` Copy all files from the `PolicyDefinitions` folder on a source computer to the new `PolicyDefinitions` folder on the [[Windows Domain Controller (DC)|Windows Domain Controller]]. The source location can be either of the following ones: - The `C:\Windows\PolicyDefinitions` folder on a Windows 8.1-based or Windows 10-based client computer - The `C:\Program Files (x86)\Microsoft Group Policy\<version-specific>\PolicyDefinitions` folder, if you have downloaded any of the Administrative Templates separately from the links above. The `PolicyDefinitions` folder on the Windows domain controller stores all `.admx` files and `.adml` files for all languages that are enabled on the client computer.
