One Windows 10 version that many people are ignorant of is Windows 10 for education, which is based on the enterprise edition. It has the ability to disable almost all data collecting / advertising features . Cortana doesn't even exist on this version. If you can grab this, and most university or college students should be able to for free, it'll be a big improvement in privacy.

Edit: from what I recall, Microsoft stated that advertising didn't have a place in education, or something to that effect
