Is it possible to add group policy settings to a windows ISO? I have certain settings that I like to set through group policy after I install Windows (like disabling automatic updates and drivers for instance), but I would like to be able to set these beforehand so I can easily just install Windows normally and not have to mess with a bunch of the settings everytime.
My opinion is this - use normal .iso and after everything is done, run for example powershell script. It's much more sensible to do this after you start Windows, maybe even after some start-up, then all the processes are already more or less stabilized. But this is my opinion and you can and may make changes as you wish.
I haven't tried adding it to an ISO, but when I'm creating images for my work I set up local group policies and replicate them by copying the "GroupPolicy" and "GroupPolicyUsers" folders from System32.
