How to transfer game bought on microsoft store to xbox

Do you mean you bought it for PC on the Microsoft Store?

Since Minecraft is not a Play Anywhere title, you would have to purchase it for the Xbox in order to play it on the Xbox. You wouldn't get it on Xbox just for purchasing it for PC.

i bought on the microsoft store minecraft bedrock edition and on the old microsoft store i saw a button which let me install it on the xbox aswell but now with the new store i the button isn't there anymore so i don't understand that and if i look at minecraft is says i can play on console and pc

It's available for both console and PC, but you have to buy it for each platform.

Hello David,

From what i know Vbucks that you have bought via the Microsoft store do not transfer to PC

It will never, never, never ever, ever happen, and I'll give you the one main reason why.

Microsoft gets a cut of every Xbox game sold, doesn't matter if its bought through the Xbox Store or from a shop, they get a cut.

If you were able to buy a game from Steam and then transfer it over to the Xbox, Microsoft wouldn't get that cut.
