> Sometimes, uninstalling Copilot doesn't take it off the list of startup apps, so when you reboot your computer, it may come back.

It is not yours anymore if you can't uninstall stuff. You may own hardware, but you do not own anything on it.

Of you can do what 3% of Deskop/Laptop users in the US did last year and switch to Linux instead.

Can you just add some settings to /etc/hosts to prevent microsoft's copilot servers from being reached?
