is there a way to link my windows 10 minecraft to a mojang account

im afraid you have to buy the correct version sorry i couldnt give good news

You could request a refund for purchase error.

Ok that's good to know thanks for telling me

Thank you for taking the time to post this on the Xbox Forums. We understand that you are seeking a way to link your Windows 10 Minecraft to the java edition.

As stated by Xbox Forums Ambassador Hydrogen Wisp, there is currently no way to do this and you would have to purchase Minecraft Java
Edition from the Mojang site.

However, if you recently purchased this, you should be able to
request a refund for this item. I would encourage you to do this if you do not plan on using the Windows 10 Edition of Minecraft.

I hope this is of some use to you.

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.
