Remove Copilot from Word

Here's the problem -- I don't have that in my preference options, even though I have the same exact Version # and license as you. I've included screenshots.

Perhaps you are using a different language version or are in another country?

This was being rolled out to different regions at different times - so your region specific version is not yet updated to include?

This is only a GUESS. Who knows what Microsoft is doing? I don't think they know either.

I'm in America using a copy in English. How can I check if that's true or where that language icon came from?

I'm in Malaysia and the check box has now appeared. This project was definitely rolled out by Microsoft with inadequate thought.
Now I have a more fundamental concern:
The check box states that I am "disable"'ing Copilot.
But of course all the code is still there on my computer.
So what guarantee do I have that the AI core is not scanning everything I am doing on my computer and reviewing/learning from it, EVEN THOUGH the interface to my work screen is disabled.
Like many users I deal with confidential information which should not be capable of being read outside my office except by my permission. Say I am drafting a contract for some project, and the name of the project, and the preliminary estimate of the cost of the project, are in my documents. If CoPilot has "scanned and learned" from my document and someone else asks CoPilot: "What will be the cost of the XX Project", they can give a figure gleaned from my document.
Microsoft should provide a legal statement to the effect that CoPilot when disabled is unable to access any information on a client computer.

Yes indeed, Tony Barry2, there is no guarantee that this information will be kept confidential, given that MS has behaved in this way already, and already enforced AI upon us Office users without our consent.

The era of Big Brother is already here and in action.
