I want to buy the Minecraft account I had in Xbox Game Pass Ultimate

Hello, Joshua. Thanks for reaching out! My name is Lucas. I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

You can buy Minecraft at any time on the Microsoft/Xbox store or at the Minecraft website. Just choose the version you want (probably the Java + Bedrock bundle, right?!) and it will show you the price for people who is subscribed to Game Pass.

But you don't have to purchase it right now. You can wait until your Game Pass subscription expires and purchase the bundle then. You will not lose your gamertag/nickname, rest assured. But if you purchase it before your subscription ends, you will get a discounted price.

Feel free to ask back any questions.

If i understand the problem, you want to buy them both an Xbox Game Pass subscription to play on their respective PC's ? Buy an Xbox Game Pass PC sub for each or a Ultimate Game Pass. Log their account on Xbox beta app on PC and buy them the correct sub.
Or use xbox.com with their account correctly sign in and buy them Xbox Game Pass for PC.

my father has a game pass ultimate. He's able to play pc/ultimate. my Xbox is home. When I try playing on the pc it asked me to buy it. how can you help me?

Are you logging in on your father's account, or your own account? Because my fiance wanted to play the Halo: MCC on the PC one time, but she had to be signed into my Xbox account in order to be able to play it because my account is Game Pass Ultimate. Otherwise,
you have to have your own Game Pass Ultimate subscription.

I have cancelled my Ultimate Pass and I'm happy with 12 months Xbox Live Gold membership I was able to purchase after the Ultimate Pass had expired. My original concern was whether or not I could just buy Gold or would it convert to Ultimate Pass after
previously upgrading to it, as I no longer wanted to use Ultimate Game Pass and just have Gold.

I dont think Minecraft is in Ultimate Game Pass or Play Anywhere on PC.... i just had a look on the Xbox (Beta) app on PC and i cant find it.... but you can get it from the Microsoft store on PC and buy it...
