That’s the thing. It doesn’t seem like you actually found a “solution“. I also disabled and uninstalled, and it still shows the Copilot icon in OneNote.
I hate to admit this, but there actually is a viable solution for me where I don’t have to stop using Windows after 3 decades of loyalty, and that is to reformat my computer.
EDIT- after reformatting and being careful not to activate Copilot, it activated anyway and now my OneNote shows the Copilot icon no matter what I do.
But here’s the deal. Going forward, I’m going to be using a dual boot or virtual machine so that I don’t have to expose my data to Windows beyond the absolute bare minimum. I hope and anticipate that over time I will use Windows less and less and just become a Linux user.
Lastly, though it seems I share your sentiment, I don’t want to come across as being abusive of Microsoft product managers and engineers. I understand everyone is in the middle of an AI craze. But they do deserve to know that Apple seems to be navigating this with much more sophistication and grace than Microsoft. I have much higher confidence that Apple is going to keep my data private. That isn’t because I know how their back end is architected, it’s because I can see Microsoft‘s commitment to opt-in policies reflected on my own computer.
