Minecraft disappeared from Microsoft account after reinstalling Windows

Yes, it is possible to install Minecraft Bedrock Edition on PC, in the Launcher it appears with the name "Minecraft for Windows".

Regarding the migration question, don't worry, your Minecraft Java Edition will not disappear, the only thing that will change is that the game license will be linked to the Microsoft account where you migrate it and after that to be able to run the game you will only have to log in with your Microsoft account instead of your Mojang account.

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.

If Minecraft won't open after signing in to Microsoft, try repairing the launcher, clearing cached account tokens, restarting your computer and game services, and checking for Windows and graphics card driver updates. If the problem persists, uninstall and reinstall the launcher.

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.

Hi Charlie,

Thank you for posting in Microsoft Xbox Community. I understand that you want to reinstall Minecraft. Please follow my recommendations below.

1. Delete the Minecraft launcher that exists on your computer.

2. Restart your computer.

3. Install legacy Minecraft launcher for Windows.

Once reinstalled, continue with these instructions.

1. Open Minecraft launcher.

2. If you are already logged in, click on your image and Gamer tag in the upper left corner of the screen and then on "Logout".

3. After logging out, delete all accounts registered in the launcher by clicking on the "X" next to each account.

4. In the Minecraft launcher, enter the Microsoft email and password.

If you bought Minecraft from Microsoft Store, you have to go to Microsoft Store>My Library then look for Minecraft and install.

Make sure you're signed into the Store app with the same Microsoft account that you used to buy the game.

If the above steps did not work, please clear the cache of the Microsoft store. Go to Settings> System> Apps & features> Click Store> Advanced options> Reset.

After the reset, log in with the Microsoft account that has Minecraft and reinstall Launcher.

Hope this solves your issue, please do let me know how it goes.

Regards,

Alvaro
