Windows 10 Privacy Settings
To find the main privacy settings, choose Settings from the Start menu. Then choose Privacy. In the General tab all the options are turned on by default. You can turn off the advertising tracking, SmartScreen Filter, and can also stop sending info to Microsoft about typing and writing.
In the Privacy area, you will also want to visit the Feedback & diagnostics tab to at least limit the data that is sent to Microsoft. In this area you can choose the amount of Windows diagnostic and usage data sent to Microsoft from your device. The choices are: Basic, Enhanced, and Full.
In this area you can also turn off the location services, the camera and the microphone. It is worth taking the time to look through each of the Privacy tabs to limit Microsoft’s access as much as you like.
