I see. Well, it is comforting to know that there's a chance I didn't waste ~4 hours today setting up templates. I'll test out the templates I've been working on and see if they work, and depending on how that goes I may just try to "automate" as much as I can using registry values (since, to my current knowledge, are easier to apply than a template).
That makes sense that some values may need to be set for individual users. I believe all of what I'm dealing with are admin-side policies/settings, so I think I'm off the hook on that.
Y'know, it's taken me a lot of time to try and "automate" all this. I hope that whenever I'm done, the amount of time it took me to work on this is still less than the amount of time that it would take to configure the computers manually! :/
Thanks for your reply, and for welcoming me to the forums
