You can use Win10Privacy to bodily castrate nearly all built-in spyware and telemetry.
Downside is that it’s a damn powerful program, with few guardrails, so if you don’t have good knowledge of Windows internals you run a non-trivial risk of accidentally lobotomizing an important feature of your install by enabling the wrong setting. I mean, all settings can be easily reversed, but you gotta know which specific one did the nerfing in order to undo the oopsie.
For example, even the midrange firewall settings are mostly safe, except… a single one of them completely kills Microsoft Office Click-To-Run. It won’t install, and it won’t launch even if you installed it before you applied Win10Privacy. So if Microsoft Office is an essential (Access or Excel absolutely needed, for example), be careful.
