You might have a Win key jammed. If you pressed the key too hard, it could have broken and caused these random turns. I don't have any other guesses. I've had occasional menus opening when I had Win 10, too. Perhaps your PC is reminding you to update your OS to the latest version? When I bought the
windows 11 license, all such problems disappeared. Windows developers have thought of such things so that all version 11 users are happy with the upgrade. After all, many of the users of Vin 11 complain at first about unfamiliar features. But since 11 is better than 10, we are getting used to the innovations.
