The services that are a part of Windows 10 itself are fairly quickly and easily turned off. You can tweak your default apps for certain common tasks, e.g., photo viewer, video player, music player, web browser, in the System Settings, Default Apps Pane. I've changed all there except Maps, which I don't use at all and the provisos of the Microsoft Services Agreement come in only when you use an app, not because it's bundled with your system.
Cortana settings are a thing of their own, and I've had Cortana disabled since the moment I've installed Windows 10, but have documented how to tweak those dedicated settings on the forums multiple times. I've also done the same regarding OneDrive.
As to everything else, it is a quick run down the Panes in the Privacy Settings. Virtually everything comes "On" but the amount of time necessary to to the review of every pane and ticking any slider switches to "Off" where you want that is around 10 minutes.
Most of the Microsoft Services in that list do not even come bundled with Windows 10 but must be downloaded/installed before they even exist on your machine. I can't be using probably 85-90% of what's on that list because it simply doesn't exist on my machine because I've never installed any of them. I didn't even know that some of them existed, or what their purpose was, until I looked at some of them after reviewing the MSA.

In a modern society where everyone thinks their opinion deserves to be heard nothing annoys me more than individuals who mistake their personal preferences for fact.
