The stuff about Win 10 being more of a spying thing from Microsoft is largely BS. It's pretty much the same as it has always been, except for Cortana.
Cortana is designed to be an electronic "personal assistant". Of course it needs more personal information to give you a tailored response, no one should expect anything different. If this is a problem for you, simply don't use Cortana.
But anyone with any kind of smart phone is being silly to worry about Microsoft mining personal information.
Hello there Sir.
As a network engineer, let me be the first to tell you that my logs indicacte that every keystroke you make in Windows is uploaded to Microsoft.
Every program you open causes yet more packets to be sent to MS, as they are encrypted, I can assume they contain the executables' attributes of the chosen program.
Furthermore, they take copies of all your contacts too - they are uploaded also.
I can see no acceptable reason for any of this behaviour, and thus I will not use it on my main machines.
There is of course other privacy concerns with Windows 10, just do a little searching for yourself, rather than making gross uninformed statements regarding a topic, for which you clearly have no knowledge of.
Peace out.
