Not received digital download codes for Xbox 360 Gears of War games?

Yes the Gears of War games are available from day one, but only if you own the digital copies or own them on disc. If you played Gears of War Ultimate on the Xbox One online since the day of release, then you will receive a code to download all 4 of the
Xbox 360 games on or after the 1st December.

According to the Gears of War 4 official site-

For a limited time, all purchases of Gears of War 4 include the entire Gears of War Xbox 360 library for free, all playable on Xbox One thanks to Backwards Compatibility! The Gears of War Xbox 360 collection provides you with four incredible games, from
the epic saga of the original Gears of War trilogy to the standalone story of Gears of War: Judgment.

Physical copies of the game will come with codes for each of the four titles to download via Xbox Live. For those who purchase digitally, your codes will be sent via Xbox Live message – we’ll be sharing more information on digital distribution closer to
launch.

Hey fxbanker,

You received a disc copy of Gears of War 4? If so, the codes should be located in the case if the bundle you purchased was specially marked. In order to receive the Gears of War 4 codes over Xbox Live, you would need to redeem a digital code for Gears of
War 4, or would have had to purchase digitally through the Xbox Store. If you did redeem a Gears of War 4 code for the
digital version, then Smwutches is correct that you will receive the codes within 30 days of the code redemption date.

Please let us know if it is not digital so we can further narrow this down!

You would have received the correct codes. As it states in the game's description: For a limited time, purchase and redeem your copy of Gears of War 4 and get the entore Xbox 360 Gears of War collection for use on Xbox One!

So the codes are meant for console use not, Windows use. Gears 4 is the only one that's available in the Windows Store, so there would not be a way to download the 360 collection through Windows.
