The best way to reinstall game and not reinstall all your games again is to go to C-program files-steam and delete everything from the folder except: steamapps and userdata and steam which will say application over to the right.
After you have deleted all but these three, double click the steam application which will then repair the steam client and you will not have to wait for the rather slow re-installation of your games.
