Some of those are stored in
HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R17.0\ACAD-xxxxxx\FixedProfile\Editor Configuration
But the information in the "profile" is stored in
HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R17.0\ACAD-xxxxxx\Profiles\<<Name of Profile>>
...and this is what gets exported to an ARG file (which is nothing more than a REG file)
They are also stored under the profile.
HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R17.0\ACAD-xxxxxx\Profiles\<<Name of Profile>>\Dialogs
When you are ready to get serious about machine configuration, forget the ARG import /export nonsense and set your desired settings during AutoCAD startup, via the "acad.lsp", "acaddoc.lsp" and/or the "acad.rx" files.
