A long time ago, I bought a boxed GTA4 for Windows. I recall that it made me register the game via Microsoft's "Games for Windows" (which I think was rebranded as Xbox Live). Does anyone know if this allows me to download the game if I want to play it again?

Your GfWL ID is only used for going online. If you bought the physical version of the game, you need to insert the disc into your PC to play it. You can download the game on the GfWL marketplace, however, if you bought the physical copy, it doesn't entitle you to a free download on the marketplace.
