I do not refer to Windows 10 positively and I will be very reluctant to install my "Free" copy.
Three reasons: (1) What was once optional is now mandatory - Microsoft is insisting that it monitors your very use of the OS and that can only be changed through modifying its registry; (2) It is mandatory that you connect to a Microsoft Account to use the OS; (3) I want to wait until the last possible moment to install this - let's see what happens in the next 6 months.
It is for these 3 reasons I am reluctant. I do not want Microsoft spying on me and controlling more of my life. I am scared. Your comments are appreciated.
