I am also having trouble disabling copilot. Along with simply not wanting the feature, I have ethical conflictions with AI because of its negative impact on the environment. I am also in a creative career so I have I have ethical conflictions with it in that regard as well. I understand it may be helpful for some, but I do not understand why it feels impossible to disable.
I called to try to disable this and was told that there was no way to address my concern via their automated assistant. When I asked to speak to a live agent the phone hung up.
I tried to contact Microsoft support via a live chat. I expressed that I wanted the feature disabled when prompted for my reason for the chat. I waited over an hour for a response despite the wait time being 13 minutes only to follow up and see that the ticket was closed before an agent even spoke to me. There were two people in front of me as well and I'm assuming they were addressed as I saw the countdown going down until I was "the next person in line" only to realize that I had been waiting for something that would not be addressed.
Not to mention how utterly distracting the toggle is. Why is this so hard to disable and why is Microsoft blatantly ignoring users/giving the run-around for those who do not want to use AI?
