To get started locating Wi-Fi Sense open All Settings and then select Network & Internet.
Just a bit further to go
Now, select Wi-Fi on the left and then Manage Wi-Fi settings on the right.
First page of settings
Now that the Wi-Fi Sense settings page has been reached, the first page shows how to turn it OFF and ON, and gives options for who stored network information will be shared with.
Pagedown for more
Now, if you pagedown, you'll find the list of networks that Windows 10 has already stored. Some are shareable and some are not.
Additional protection for known networks
For those that are shareable, just tap or click on the record and choose to Share or Forget.
