I use windows 10, I don't have a brand new computer ... but I shut off every spying app I could find as well as cortana. I also opt out of personalized ads. I do this on my phone as well. And on facebook.
Every once in a while, I check my settings because it seems to me, after updates, that these settings mysteriously change.
Good luck..
I followed a couple of bloggers and their opt out diagrams. The actual physical computer setup was OK. It's the office suite I can't use. So, I pretended to make an account to get to the privacy policy which, in essence, says MS can use anything you upload to further their own ends. You give them an unlimited right to use your content. How can businesses agree to this? My biz info is proprietary.
And, yes, I realize email is not secure. And my email address is associated with everything l'm saying here, and I've said a lot! And my new phone tracks me everywhere I go. It's just a bit overwhelming.
The problem is, now this account is associated with this computer and it can never be used again. If I get a new computer, I need a new account, which kind of defeats the purpose of tracking me from cradle to grave.
I read 5 pages, out of 33, of complaints to MS from small computer company techs who cannot set up computers for clients without asking them for personal info, copying their passwords, or setting them up with accounts they'll never remember. Plus, MS says you cannot lie in setting up an account. Seriously? Back when this was my actual job, you think I would be asking for birthdays and zip codes from my hundreds of clients? Yeesh!
Ok, off the soap box. I created an account for a fictitious person who will be forever 21. Unlike me.
