I would like to buy the Minecraft Java Edition for my laptop soon, now I wanted to ask if if I buy it I can later download the Minecraft Java Edition free of charge for my next laptop / computer with my Microsoft account?
Not with your Microsoft account but with a Mojang account.
Minecraft is not in the Microsoft store…
Well, I also have the Mojang account, so is that okay?
Yes. Simply download the launcher then log in with your account, done
OK thank you
Please please.
A little confusing, anyway
To buy Minecraft Java you first need an account which you create on minecraft.net. If you then bought Minecraft you can download it to any PC / laptop again. You just have to be logged in to minecraft.net with your account. If you downloaded it (the launcher) you will have to log in again to play Minecraft.
