before you do anything read this
How can I disable communication center so that it wont be active when AutoCAD starts?
Not real sure about that solution posted by Ritch. Sounds pretty suss to me. I don't have coms centre display when I fire acad up. But I vaguely remember something about it. Just go to acad help and see what it says. I'm sure, from memory it was as simple as unchecking something in Tools > Options.
you can do it options way, but if you read the link properly it is better to do it that way
Although it looks sus, it is a perfectly viable option, although I tend to keep quiet about regedit, the fewer people that know about it, the better.
In options, I think you may be thinking about live enablers.
EDIT: Nice Googling Ritch.
In ACAD, click on the satelite icon (com center) then settings, and where it asks for checking for updates, set Never.
