Eh, back in the Windows 7 days paying for Windows wasn't that bad of a deal, but starting with Windows 10 it felt as if you were paying to get ads.

As for your last part, I am not a native english speaker, and my phone has two dictionaries, sometimes it picks the Swedish dictionary, sometimes it picks the English.

I have been in situations where the dictionary marks a word as being wrong and offers a suggestion, when I then pick the suggestion, that word is also marked as being wrong, and the original word is offered as a solution.

This can be rather annoying, and means that sometimes stuff like this slips through.
