I agree that both telemetry and Cortana both suck. I didn't realize that you could now turn of Cortana because I was using the registry key to do it before. There aren't really a whole lot of new features though. There are a few nice ones like having SSH bundled, curl, and a more polished UI. Windows 7 was a steaming pile. As far as I'm concerned 10 is a lot better, other than Cortana and giving away all privacy. Though if one truly cared about those things, they wouldn't be using Microsoft software to begin with. They worked with the NSA on Vista. I have no reason to believe anything has changed in that regard since then. Therefore it is safe to assume the software is completely untrustworthy.
