En parallèle de la mise à jour du Source engine, Valve Software corrige quelques bugs gênants qui étaient encore présents dans Steam, sa plateforme de téléchargement et d'utilisation d'applications.

La principale innovation apportée par ce patch est la possibilité de désinstaller des jeux téléchargés via Steam dans Ajout/Suppression de programmes de Windows.
