You're right @37712 , if you use Windows it's not your computer, you're a renter. It's been possible for Microsoft, & therefore all 3-letter agencies, to remote control in since at least Windows 7.
And it's been phoning home telemetrics for alot longer than that. Also, Intel chips have out of band privileged access to EVERYHING through it's TPM which is why you also need to be choosy with your hardware.
None of this proves you're not crazy though.
