I don't think Windows (or any OS) is 'loved' by the vast majority anywhere. It just happens to be what comes on most PC's and so that's what people use and that's what the manufacturers make hardware and the software guys make games and programs for.
It's generally those who make a conscious / active choice to 'buck the trend' (for whatever reason) to seek out something else who are more likely to refer to an OS with an emotive term like 'love', simply because they are obviously more interested in such things than most (and therefore less likely to have lives and girlfriends etc). ;-)
Ask most ordinary computer users (who aren't interested in 'computers' in the main) what OS they are running they will generally say 'Huh?'. Some might say 'Windows' but not have a clue what version, many might say 'Office' (because that's all they generally use their computers for) and you will be able to tell the (comparative) nerd when they say 'Windows 10 Pro 64bit', 'Linux Mint 17.3 Cinnamon' or 'OSX 10.11 - Badger' (or whatever stupid / surplus name they are up to now).
And that's typically where the trouble starts, as soon as someone takes an interest in something that in an ideal world should be transparent (an OS), you start to get people who think other people 'love' an OS or even care about said. Of course they don't, like me and many others they just want something that works and allows them to do everything *they* want to do, not what some OS restricts them doing. So, no one I've ever offered Linux to seems to GAF that it's 'free' or 'more secure', if it doesn't (for example) run their favourite web game or access the iTunes music store.
It's just the same as people who say they 'Wouldn't have a Ford' (when Fords obviously work for millions of people) or wouldn't have an iDevice when there is a good chance they have never really tried one or have a need for any .mp3 player.
I have owned many makes and models of car, mp3 player and all sorts of things many others seem to get all excited about and they *all* have their pros and cons.
The bottom line (excuse the pun) is seeing what things seem to work and what things don't. Apple have sold millions (if not billions) of iPods worldwide and I'm sure most users are still very happy with them (it's still the most common mp3 player I see of those people not streaming stuff via their phones) and they did so because for yer non-geek they were about the only thing they could get working.
