@roamer_1 I'll be PMing you when I get my new Lenovo back from the Warranty shop in a week or so. There is a lot of crap to cut from a factory machine. Scores of background processes running, I'm sure most of them are BS.
@Cyber Liberty You are welcome anytime...

There isn't much you can do if you are signing into MS and using Cortana, and etc...
But if you can live with a local login and a bunch of the happy birthday crap turned off, all you really need is
Shutup10.
Download it, make a folder in the root, drop it in there, and run it.
When the dialog comes up, choose the 'Actions' pulldown and poke the yellow option.
close the program. it will ask to restart the box, and when it comes back up all the telemetry to MS will be gone.
You will need to update the app now and then, and you will need to run it after any major update to Win to reset what MS turns back on...
Because Win is always updating and changing, I am not much of an advocate for custom trimming and hacking, because keeping track of it becomes pretty impossible... That's why I recommend Shutup10, as it is the easiest way to do a pretty good job...
Additionally DL O&O
Appbuster, drop it in the same folder, and run it...
It will give you incremental and excellent control over all of the apps included in Win10 - a one-stop way to uninstall, reinstall, disable, enable all of it.
Between the two, they make managing the impositions of WIN10 a breeze.
