As part of the ongoing celebration of the 12th anniversary of the Command and Conquer series EA decided to make the game Command and Conquer Gold freely available to the community. Both iso images - one for GDI and one for NOD - that are available on the official website and numerous other download sites have a size of about 550 Megabyte and are fully compatible with Windows XP.
The iso images have to be burned to CD or mounted using a software like Daemon Tools. A patch to make the version compatible with Windows XP has to be downloaded as well from the official Westwood ftp site. The game is well worth the download in my opinion even if it lacks modern graphics and user interface.
Below are the instructions found in the read me that explains how to configure the game to play it in Windows XP:
I would suggest to use a download manager to download both iso images because it really takes a long time to do so. I do get about 10K per second at the moment.
Update: The Command and Conquer Gold game appears to be no longer listed on the Westwood server. You can still download the full game for Windows from third party sites such as Gamers Hell where ISO images of both sides in the conflict and a patch is available. Note that the full download has a size of about 1.1 Gigabyte.
