Windows 10 Pro, I've installed it about 40 times or more. Domain Join is the option to create a local account. It works, I do it every install, while connected to network.
>It's like healthcare in the US: Since people can't opt out of it
We do not have a national healthcare system as most of the world does. We are not forced to have healthcare. Yes there are provisions of Patient Protection and Affordable Care Act that charge a tax penalty if you are not covered or exempt.
>I don't know the realities of the weird city life Americans experience, but the places I've lived in Europe make this trivial.
I have lived in poor rural America. Here is some information for you that might help: There are no forms of public transportation. You are required to own your own car or have someone drive you. Work is usually 1 hour or more away. The grocery store is usually 30 minutes to 1 hour away. There are usually fast food restaurants within a few miles. Don't forget that America is gigantic in area and very spread out in the rural areas. However after telling you this, when I was a child we did go grocery shopping and ate things like crock pot roast beef and hamburger helper.
