Most software that you buy directly from Microsoft comes as a digital download that you can download, install, or reinstall. After you purchase software, the download will be shown in your Order history. If you used the same email, of course.

The main thing that really matters for account and game usage is your email address. I highly doubt Microsoft will do anything to you for putting in fake info, as it's not their problem if you do... it's yours (unless you are stealing someone else's identity, in which case they will act if the real person you are stealing from notices and opens a case). You will probably face issues with account security and recovery, as setting up things like two-factor authentication requires your actual phone. If your account is hacked, you can't prove it is yours since you will need to provide proof you are the account owner (since this information is faked, any proof you provide will only prove you aren't the "real" owner).

Fredy31 was right it was an outage

If you want to play the Windows 10 Edition, you still have to buy it even if you have the mobile game with a microsoft account. I have bedrock edition on my phone, Nintendo Switch, and Xbox, and I have always had to buy Minecraft on each device.

It is possible to use Game Pass for PC in a game-sharing setup, but all involved PC accounts must be signed in to the same account via the Windows Store. I reached out to Microsoft Gamer Support, who confirmed that you can not be logged in to both PCs at the same time. Can I use my Xbox Live Pass Ultimate Subscription on multiple Windows 10 devices? Yes, just like Xbox Live Gold or Xbox Game Pass, you can use this subscription wherever you sign in. Your subscription is tied to you, not to a specific device. - Xbox Game Pass Ultimate FAQ "You can only do so one at a time. It will log you off when logging on a different pc." - Microsoft Gamer Support Ultimately, you have three options: Log in to your account via the Microsoft Store on your son's PC, and arrange a schedule so you are not both trying to play Game Pass games at the same time. Purchase your son his own Game Pass for PC subscription Forgo Game Pass for PC all together, on your son's PC, and hope that they release some sort of sharing bundle, in the future. The different Xbox applications shouldn't make any difference; to clarify, both applications are the same. You have the beta version, which is an older pre-release version; your son has the newer version, downloaded directly from the Windows Store.

:< sadly.. I don't think they can be used directly .. the save file's structure is different between 2 version. Hope the will be some app to convert between them soon xD.
