The problem with a one-click approach is that one person's "legit feature" is another person's privacy nightmare. I have no use for Cortana, so for me, it's nothing more than an annoyance to be disabled. But for others, it might be the one reason why they upgraded to Windows 10. Likewise, some tutorials out there advocate disabling Windows Defender, but I consider (at least some parts of) Windows Defender to be a legitimate feature. I'm trying out Windows 10 in a VM, and so far I've managed to disable: everything in the privacy control panel, advertising ID in Edge, Cortana, OneDrive, web search from the taskbar, feedback, telemetry, and the half-crippled Start menu. Now it's just a slightly faster and flatter Windows 7. I'm not sure if I'll ever let it out of the hypervisor though.
