I don't know if any of you plan to 'upgrade' to Windows 10 (Not me for a while - I always wait until the dust settles) but some of the tech sites are running various articles, one which piqued the interest of some of my mates in the world of computers is this;

By default, Microsoft gets to see your location, keystrokes and browser history -- and listen to your microphone, and some of that stuff is shared with "trusted [by Microsoft, not by you] partners."
If anyone has any interesting articles regarding the use of Windows 10, please share.
