I keep getting asked about Windows 10 privacy, especially since Windows 10 is now a great deal more user-intrusive than previous Microsoft operating systems. Intrusive sounds a little strong, perhaps, but the truth is that the OS will feed back more data than perhaps users would like. Microsoft is not alone in this hunger for user data. Google is one of the largest data harvesters, along with Facebook, etc. Those businesses love your data. It allows them to profile the users and deliver advertising and targeted results. If you don't want that data harvested, don't use their services. However, in return for using their services, users should always ensure their privacy settings meet their expectations.

Anyhow, back to the topic: Windows 10 privacy settings tips.

Installing Windows 10 is relatively easy for most people, and that's the issue. For many they will just take the default settings and set off the upgrade, or accept default on their new computer. In the upgrade process, users can select the option to customise what data is sent to Microsoft. Choose the Customize Settings option with an upgrade, or a new installation.
If you did accept the defaults, you can go and change the default privacy settings.
In addition, if you did choose the the custom settings, there's a limit to the options, so it's worth reviewing the settings after the installation is complete. You might be surprised by the number of options that are still on, or that can be tightened.

Here's what you can change, and here's how.

Go to Settings > Privacy
From there you have a range of options, starting in the General section. You can also change other aspects, such as Location, Camera, Microphone, Speech, Inking and Typing, Account info, Feedback and diagnostics, background app, amongst others.

One of the settings you might want to alter is Feedback and diagnostics, and change "Send your device data to Microsoft," switching that to the Basic option.

Go through the list and make your selections, but do remember that some of the settings will be beneficial to the user. You can always go and change the settings any time.
Try turning it all off, or at least as much as you can within the user control, and slowly turn on everything that you think you might need, as you want to use the applications.

Here are some reference documents from Microsoft which explains more about what data Microsoft collects and how you can control it.
