Not to the extent you've signed away all of your rights.
You do agree to the terms of the software to USE the software, but frankly if it ever got to a court, chances are the court would insist there always be a way to turn it off. True, MS could infinitely play games with updates turning it back on, and make you keep turning it off again, but reasonably they're always going to have to at least provide a way to turn it off.
The one that has me concerned is the current version of activation, if only because they've polled your hardware in some unspecified sense even before any of this, matched it in many cases to a BIOS key (if you have one) and an MS account (admittedly optional if you insisted on a local login), and then placed it in a central database (IP and geo tagged to be sure). It's unspecific in many ways, sure, but there's no opting out of any of that (other than the MS account).
