Never get a windows 10 minecraft code from Mojang

When you redeemed your Java Minecraft on Mojang, you have gotten a 5x5 code to redeem Minecraft on the Windows 10 store.

This redemption is a separate service of your Mojang account, and it's possible to use a Microsoft Account email that is different from your Mojang account email.

Mojang (which gives you Java Minecraft) is separate from the Microsoft Windows Store App, which uses a Microsoft Account email when you redeemed that 5x5 code.

After redemption of that code, the Windows 10 Minecraft is tied to the Microsoft Account email you used on your Windows 10 PC. From then on, you don't really need the Mojang account anymore, if you only want to play on Windows 10. You will then get the game
from the Windows 10 store only, with the E-Mail account you used on the Windows 10 store during code redemption.

So make sure you are signed in with the Microsoft Account email (which might not necessarily be the Mojang account email) when you use the Windows 10 Store app to re-download your Windows 10 Minecraft again.

Players who already have the previous PC or Mac edition of Minecraft (running on Java) can
download Minecraft: Windows 10 Edition for free.

Note You'll need to get a code from Mojang, the game developer, by signing in to your Mojang account before attempting to redeem your code for Minecraft: Windows 10 Edition. Otherwise, you
may incur a charge. To get your code from Mojang:

1. Sign in with your Mojang account.
   
2. Under Minecraft: Windows 10 Edition, select the link to request a code. Microsoft Windows 10 will open.
   
   Note You'll need to sign in to or create a Microsoft account. If you sign in, use the Microsoft account you use to sign in to your Xbox account.
   
3. If you're running Windows 10, you'll be able to download the game right after redeeming your code. If you're running an earlier operating system, you'll need to come back to Microsoft Store once you're running Windows 10.
   

The code you receive from Mojang will be kept on your account, in case you’re unable to redeem it straight away, or in case you have problems trying to redeem it in Microsoft Store.

Hi MK,

Thanks for asking this question on the Xbox forums. In regard to any codes for a free version of Minecraft for Windows 10 with the purchase of Minecraft Java version, that would need to come directly from Mojang. According to their website, "Players
who have purchased Minecraft: Java Edition before October 19th, 2018 can get Minecraft for Windows 10 for free by visiting their Mojang account."

Should you like to check your ability to claim this code, I recommend following the instructions provided in the Mojang Support article entitled
Minecraft for Windows 10.
If it is determined that you're not eligible, then you would need to purchase that particular version in order to use it.

Give this a try and let us know the results.

I hope that this helps you out!

Hi Airwreck14,

Thanks for reaching out to us in the forums with this question. In regard to the Minecraft: Java edition, if you purchased Minecraft: Java Edition before October 19th, 2018, can get this edition for free by requesting it from Mojang. If you did
not, then you would be required to purchase the Minecraft: Windows 10 edition in order to obtain that version of Minecraft & change the skin. Minecraft: Java and the Windows 10 version are 2 separately coded versions of the game.

This article from Mojang Support can help further explain why this is happening:

I hope that this helps out. Let us know if you have any further questions.
