A dear friend of mine who handles a department of 200+ computers on a network helped me out with my new Lenovo Yoga Laptop and tablet that runs Windows 10.
He installs "Shut Up Windows 10" on all the new department computers. It does a wonderful job of shutting out the "spying" that Windows 10 does and much of the background functioning.
Your mileage may vary, so do your research before you install. I have no problem endorsing this free program to others because it makes my new baby computer run faster and knocks out the sluggishness that many complain of.
