Administrative Templates (.admx) for Windows 11 Sep 2025 Update

Administrative Templates (.admx) for Windows 11 Sep 2025 Update, published by Microsoft Corporation in version 11.25H2, supplies the complete set of policy definition files required to centrally configure Windows 11 25H2 systems through Group Policy. The package contains every .admx and corresponding .adml file that maps the operating system’s new security, privacy, and productivity settings to editable Group Policy objects, enabling administrators to enforce registry-based configuration without manual editing. Typical use cases include locking down the Copilot experience, managing updated Defender attack surface reduction rules, configuring the revised taskbar and Start menu defaults introduced in the 2025 feature release, and standardising TLS cipher suites across enterprise devices. Because the templates are language-neutral with localised .adml files, multinational environments can apply the same baseline policy while still displaying administrative explanations in each region’s language. The release is offered alongside a second versions bundle that retains backward compatibility for organisations that maintain mixed 24H2/25H2 fleets, ensuring that policy definitions remain consistent when domain controllers or management stations have not yet been upgraded. As an essential component of the System Administration category, the 11.25H2 update is distributed as a single Microsoft-signed cabinet that expands into the central PolicyDefinitions store, immediately making every new 25H2 setting visible inside the Group Policy Management Console. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
