It's actually so easy I've forgotten how I did it, but I removed all of that stuff (including Cortana) within the first 5 or 10 minutes of booting into Win 10 for the first time about 3 years ago. I think you just right-click on it and remove it.
Much of the hate towards Win 10 is just FUD from people who didn't bother to try even basic things to customize it to their liking before claiming it can't be done. I let that get to me and held off on updating from 7 for awhile, but I've been on 10 for a few years now and it's been rock-solid and problem-free.
The biggest problem - automatic updates that take over and restart the computer without your permission, potentially bricking it - is something that I avoided by getting Pro. There is some merit to the argument that your OS shouldn't by default delete your work, run code without your permission, and possibly brick your computer unless you pay.
It is a very good OS worth the cost, and if you do pay for it then that's not a problem at all. But the fact that they take such a bludgeoning approach on the people who get it for free does still seem wrong. The reasoning behind it makes sense though (almost all users are online and need updates for security or else their compromised machines become part of the problem). And the solution, pay to control when updates occur, doesn't make sense at the technological level, but at the human level it does. Those who care enough about it to pay for that are the ones less likely to be security problems.
