The bad news IMHO, MSFT has an intrusive pop-up followed by a message in the notification area which has to be dismissed. The good news is that it does not appear to be installed and even better, if you have a local account it can’t be used. But still, I don’t like the nag at all.
“To get started, press + C, or use the Copilot in Windows icon located on the right end of the taskbar. If you want to show or hide the icon from your taskbar, right-click on the taskbar then select Show Copilot (preview) button to clear the checkmark from the option.
Note: If you’re signed in with a local account, Copilot in Windows isn’t available.”
