Ghacks has reported (as had Neowin) changes in privacy in W10, which has been a concern of Windows users for a long time. "You can load https://account.microsoft.com/privacy#/ in your browser of choice to open the new "Your Privacy" page on the Microsoft Account website." - gHacks
"In a nutshell: Microsoft will improve the privacy set up experience and privacy settings in the upcoming Windows 10 Creators Update, and it has launched a new online privacy dashboard that Microsoft customers can check out to control collected data...
The privacy dashboard on Microsoft's website lists data from four sources currently:
- Microsoft Edge browsing data. This is only sent to Microsoft if you are logged in to Windows with a Microsoft account, and have turned on browsing history in Cortana.
- Bing search data. When you search on Bing while being logged in to the Microsoft account.
- Location information taken from Bing and Microsoft Health GPS-based activities.
- Cortana's Notebook reveals your interests.
You can clear the data directly from the privacy website. Each page lists frequently asked questions on top of that." - gHacks
Not as much control as some would like, but still a step forward.
I'd suggest you read the article on the gHacks website (ext. link) for more info.
