If you followed the instructions in this guide, you're now using a version of GTA IV without any modifications. Logging into Windows Marketplace enables you to save as Rockstar intended you to save and you can also use the ingame-phone to start multiplayer matches. If the Windows Marketplace prompt doesn't open automatically during the load screen for the GTA IV main menu, try pressing the home key if you have a QWERTY keyboard or the POS1 key if you have a QWERTZ keyboard to open it. It will ask you for your product key, simply paste the key you copied before. Check all the boxes provided so you don't have to sign in manually every time you start GTA IV.

Also, copy the GTA IV-Key before starting the game, so you can paste it into Windows Marketplace afterwards. For this step, it is important to remember the account details which you used during step two to sign into the XBOX app.
