Actually, it is important to upgrade to Windows 10 or any other updates to Windows because each iteration of Windows has additional cyber security measures over the previous ones, sometimes taking into account new features in the Intel CPU hardware. I would like a simple single, privacy selected option. Also, I want to be able to turn Cortana off. But in my case I run mac with Parallels VM running Windows 10 as a guest so not so much of an issue.
