Install Windows 10 and you'd think that the operating system is locked down with maximum security turned on by default. Sadly, it isn't. Apps are configured to talk to each other, your data can be shared online and information is sent to Microsoft about your PC, activity and application crashes.

There are tools to help lock this down and Win10PrivacyFix is a commercial version.

When you first launch Win10PrivacyFix you'll see some recommended automated options. You can deactivate all communication to Microsoft, chose from a mix between security and allow apps to run smoothly or if you've made far too many changes and can't remember what you changed, you can use Win10PrivacyFix to restore the Windows 10 privacy settings back to the original defaults.

What can be switched on or off? There's a huge number of options including turning off tracking, preventing apps from gaining access to your microphone, or automatically recognising of yourself (or other people) using your apps and much more.

There's also plenty of advice and Win10PrivacyFix will suggest whether an option should be switched on or off.
