Re: Now get rid of Cortana
If you don't want to mess with regedit etc. Just grab Shutup10 from :
Just run it (no installation needed), select the recommended settings, apply, and restart (don't have ti restart, but some changes only kick in after a restart).
It disables Cortana, removed the Bing/Internet searches from the Start menu search box (so is back to just local searches), disables metrics etc. (It disables more than is done by following the privacy settings in Win 10 itself), and a bunch of other stuff.
You just need to remember to update it and run it again after any major Windows Updates, as those will sometimes re-enable things like metrics again.
