Did you know that Windows 10 has a veritable keylogger? Here is what Microsoft has to say about it:



"When you interact with your Windows device by speaking, [handwriting], or typing, Microsoft collects speech, inking, and typing information – including information about your Calendar and People [contacts]…"

If you object to this, there is a way to turn it off.

Click on the Start Menu, then open Settings.
Click on Privacy settings, which you'll find in the very last row of the menu.
Once you are in the Privacy menu, click on General
Under 'Send Microsoft info about how I write to help use improve typing and writing in the future' – Turn it to Off.
Now move ahead to the 'Speech, Inking and Typing' menu and click Stop getting to know me. This will help you turn off the speech tracking through dictation or Cortana.
