The Windows 10 privacy saga continues, this time with watchdogs claiming that Microsoft might be using the operating system to snoop on users and read their emails or access certain content that’s stored on their PCs.

Basically, it all starts with the updated privacy policy that came into effect on August 1 and that claims that some information might be collected from Windows 10 devices in order to provide a more personalized experience.

Cortana, for example, can monitor “your types and handwritten words,” but that only happens in order to “help improve and personalise our ability to correctly recognise your input.”

This does make sense at some level, especially because Cortana was designed to be a personal assistant from the very beginning, but privacy groups warn that Windows 10 can always turn into a modern Big Brother than can be used to monitor users.
