Microsoft account not working in Minecraft: Windows 10!!!

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.

In order to be able to play Minecraft dungeons on pc, you will need to purchase the windows 10 version of the game.
Buy Minecraft Dungeons - Windows 10 - Microsoft Store

oh ok well that is kind of dumb and it should work with the same microsoft account but wait what about the cloud save of a character.

Sign in the Microsoft Store with the old account. Then, install "Minecraft for Windows 10", it should be free. After that, sign out your old account from the Microsoft Store. Open up "Minecraft for Windows 10", then sign in with your new account. You will
get updates for free if you do the following. I hope this helps.

But if it's Minecraft for Windows 10 you should be redirected to Microsoft Store which will require you for a Microsoft account.

I could not find and download Minecraft Windows 10 Edition in the Microsoft Store app.

Edit: didn't work on downloading the minecraft launcher
