I have the Xbox Gamepass Ultimate, and I share the account with my brother (same household). I can play the games from the Gamepass on both my Xbox and PC so far so well. But my brother got a PC yesterday and can't install the games. He is prompted to buy it. This is not a problem on his Xbox, he can also download and play the games! My question now is how do I get my brother to play the games from the Gamepass on the PC? Greeting
Since it is probably your account with the Xbox Game Pass Ultimate subscription, he must be signed in to your account or he can buy his own subscription.
Sharing the Game Pass on the PC does not work. This is quasi Xbox exclusive.
