There is no native, supported script, registry tweak, or unattend.xml setting that will restore the classic File Explorer ribbon (like Windows 10) in all versions of Windows 11. Microsoft completely removed the legacy ribbon code from Windows 11 as of version 22H2—making all old workarounds (including registry and direct DLL hacks) non-functional on modern builds.
Key Points
There is no unattend.xml directive for enabling the classic ribbon bar. It is not configurable via answer file scripting or DISM.
Registry tweaks that enabled the ribbon in early Windows 11 builds were disabled by Microsoft and do not work in any recent official version.
The only reliable way to bring back the old ribbon consistently on all Windows 11 versions is via third-party tools:
ExplorerPatcher (free, scriptable via silent install and config)
Optionally, pre-configure settings by placing the ExplorerPatcher config file where it expects it.
No Official Ribbon Script for All Windows 11 Builds
Direct registry or DISM tweaks will NOT work after Microsoft's updates; they are ignored or may cause instability.
Any online "ribbon reg file" that claims to work on all Windows 11 is outdated or will fail on post-22H2 releases .
Summary
You cannot use an answer file or script to restore the old ribbon on all Windows 11 versions natively. Your only robust and maintainable solution is to script the installation of a tool like ExplorerPatcher in your unattend deployment. This achieves your goal reliably.
