Games for Windows Live CD Key for a Game

Yea, I know, but the CD key is entered into the Games For Windows Live thing.

If you downloaded the game using Games For Windows Live, log into Games For Windows Live and next to Play there should be an option for CD Key.

If you downloaded the game after the GFWL Marketplace was closed, unfortunately a CD-Key is not given with it as they do not want any new players to start with the servers being closed on July 1st, 2014

Hi,

Sorry, there's no way to find out the CD Key for a game if you don't have the game in front of you any longer. If you purchased this game from STEAM or Games for Windows LIVE Marketplace then the product key will be listed in either of the two platforms. If
you purchased this game via a retail platform on a DVD then there would be no way to get that CD Key if you've lost it.

Microsoft Games for Windows Live store was discontinued years ago. You can use your older keys to activate games on Steam for free if you still have the CD Keys written down somewhere.

This is assuming that you are using a downloaded version of the game.

• Go into the Games for Windows Live program on your PC.
  
• Click "Downloads"
• Click on the game (Halo 2)
• A drop-down will appear with "View Game Keys" at the bottom.
  
• Click on "View Game Keys", and that will show you the CD Key.
