How do I play these games on my PC?

[Trash Man]

I'm trying to find out how I play these games on my PC. Do I have to download it on the 360 first? I can't seem to find anything on it.

Also for the achievements for spending time playing the games, do you get a time counter and if I play for a few hours on the PC and then a few on the 360 will they be combined?

Thanks for any help.

Just go on the Games for Windows client marketplace and the Game Room download should be there.
