I was going to suggest the same thing. ZeroTier has been an absolute dream in eliminating the necessity for traditional gatekeeper services like TeamViewer or Hamachi.

How did you disable it? I disabled TeamViewer's "Start TeamViewer with Windows" option months ago (I only used the software that one time). I just checked now - the option is still disabled but I see the TeamViewer Windows service is running, exposing my machine to god knows what. Really irritating.
