You are likely familiar with Kim Komando (or at least heard of her). One of the recommended programs on her website is "O&O ShutUp10". Some may find it handy.
I turned off all the Win10 spy-crap on my mother's Win10 laptop using the built in tools and it takes awhile to do it.
The most interesting thing when turning all that spyware crap off is when running CCleaner, it will no longer re-find a bunch of web-related junk to cleanup with the spyware off. Whereas if you turn all the spyware back on, run CCleaner to clean the junk, and then click Analyze again all the crap is put right back on the computer like you never ran CCleaner - you can do this over and over and over again and you won't win the fight. So in that sense you can see that turning it off is actually doing something, although Microsoft won't let you turn everything off as there's supposedly some undocumented spying they're doing.
There's an ex-Microsoft employee that has a YouTube channel talking about the spyware in Win10:
Even though I had turned off access to the laptops webcam and microphone in the Win 10 privacy settings, Microsoft seem to think that this shouldn't apply to their own software.
I noticed when I looked at Silverlight (for a different reason) that it was still using the camera and mic. even though I had turned them off in the settings.
Simple solution to that one, go into the device manager and disable them.
