I don't expect third-party desktop application developers to continue supporting Windows 10 until 2034, given that the IoT Enterprise license agreement prohibits desktop use. Which is not to say most applications won't continue to run, but it wouldn't surprise me if, say, Valve stopped supporting Steam on Windows 10 in five years or so, as they did with Windows <10 last year.
