Microsoft continues to refute that it is shutting Games For Windows Live down in July. In August of last year a support update on Xbox.com stated, "Games for Windows Live will be discontinued on July 1, 2014". That message was later removed and Microsoft has denied that it is shutting down the multiplayer service for PC games ever since.
"We are continuing to support the Games for Windows Live service," it said in a statement issued to Game Informer. "We remain committed to investing in PC gaming in the years ahead, and look forward to sharing more in the future."
Microsoft closed its PC Marketplace in August of last year, but left an option for those who purchased content to have access to it, as well as title updates for games that use the service.
While many games have been transitioned to Steamworks and away from Games For Windows Live, there are still some games that use it like Bandai Namco's Dark Souls....
