You’re probably anxious to play, but wanted to let you know of a small problem (fortunately, with an easy fix). When you first play Gears of War for Windows, an automatic update to Games for Windows -- LIVE will be downloaded. But after the update is downloaded, you’re put back to the main menu of the game. If you don’t shut down the game, the update won’t complete. There’s two ways to get over this bump. The easiest is to simply shut down the game after the update is downloaded (you’ll know it’s safe because you’ll be back at the main menu, and not on the “Don’t shut down your PC while the update is being downloaded” screen). As soon as you close the game, the update will install automatically and you’re good to go. The second option is to manually install the latest Games for Windows -- LIVE update, which you can find here.
