Download the iso and install home. It won't stop you, ask for a key, or attempt to activate later. It just installs, runs, and spies happily.
But, yes, I suppose that you're supposed to pay for it, but they don't seem to care that much, if at all.
I agree that Windows Pro is a slightly better experience than Windows Home, but the right Linux distro for you is where it's at. I usually recommend Mint for newcomers, and not one has had issues (beyond the expected "this looks different" comments). I've installed Elementary for one person who came from a life of Mac, and she dove right in with almost no hiccups. Know your audience, I guess is the lesson here lol
To pta, yes. To Lemmy, no.
