Whenever I launch GTA-IV (via Steam), I'm prompted to "log in to Social Club". I'm not interested in multiplayer or video uploading features, at least at the moment; how can I stop this window from appearing every time I try to launch the game?
It is not possible to get rid of that screen via steam. Game will check if you have a working net connection, everytime it starts via steam. So, it will ask for you to log in to social club everytime. If you start game, without an internet connection, it should not ask for the same.
