I think Group Policies are a very incomplete, partial solution. As you said, you usually have to combine it with a few more things to get the job done, and that is how any sysadmin job works. But: You need not only a one-off-script to make things really work. You need a script that is idempotent, so you can execute it on all your machines and maybe do a retry or two if some are unreachable or an error happens. So the script should not only change things it is supposed to change (e.g. append a configuration line somewhere) but also check if that action is necessary or already done (e.g. that line has already been appended). Then you maybe need to restart the respective service to reread it's configuration. But of course you wouldn't want to unnecessarily restart it, since that might be disruptive or expensive, so you have to check if that configuration has been changed or not before restarting. Then handle automatic application for machines that are currently offline, have just been installed or need a refresh. Add in a some templateing and parameters, different groups, logging success/failure and you are at quite a complex script. Or rather, a script that no-one should write, because it is exactly what configuration management is supposed to do. If you are writing all that by hand for each one-off, you are doing it wrong because you are reinventing the wheel, and usually badly. If you aren't doing all that, you are missing important parts. So imho configuration management like puppet, salt, chef, … is table stakes for any kind of sysadmin work. I'm not familiar with Windows DSC, but I find it strange that you dismiss it as pandering to the Linux crowd.
