Given that your stated alternative was home users, you seem to have excluded just about the entire world of small businesses with that definition. They might not have dedicated IT staff, but they still need to be able to administer their systems and in many cases a designated person will still be responsible for doing so. They just need to be able to do that as well as fulfilling whatever obligations they have in their primary role. Issues like privacy and security apply just as much in this context as in a large enterprise deployment with a whole department of dedicated staff to run it, but they need simple, transparent mechanisms for setting up the office network, deploying updates to the OS and installed software, etc.

And the answer is, “IT specialists supporting Windows in corporate environments.” Generally speaking. I honestly cannot understand the motive or purpose for the rest of your comment, which seems to be about the needs of small businesses, which is not germane.

Right, because I am specifically talking about IT specialists, who “administer Windows professionally”. This is the usual definition of “professionally”, that you “profess” to do something. If I talk about people who “write professionally”, this also does not include people who happen to write emails, memos, and other ordinary correspondence at work.
But this doesn’t really exclude small business, since it’s common for small businesses (and medium) to contract IT services.
I’m not talking about people who happen to use Windows in a professional setting. I’m talking specifically about people whose main job responsibilities include Windows administration.
