... I am transferring a Minecraft world from xbox one edition Minecraft to Java edition and Windows 10 edition.

The Minecraft Xbox One Edition only works on the Xbox One Edition.

You might want to upgrade to the Minecraft (without Xbox One Edition in the name) on your Xbox. If you bought Minecraft Xbox One Edition digitally, you can upgrade to "Minecraft" for free.

Then you can import your world from the Xbox One Edition to "Minecraft" for Xbox One.

However, the Support page for Windows 10 Minecraft states: "The Windows 10 Edition does not currently support the transferring of worlds from other devices."

So you can't transfer your world between devices.

You might have to move your World to a paid online Realm server to access it. Or you might have to run your Xbox One Minecraft in Multiplayer, and connect to the running world on your Xbox One with your Windows 10 version.

But you can't have your World separately transferred from Xbox to other devices.

As I said, you can try hosting your world on a Realm server (which you need to pay for), and can then access it with Windows 10, Xbox One, Android, iOS and Nintendo Switch.

But not JAVA.

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

Edit: didn't work on downloading the minecraft launcher

The original Xbox Live has been shut down.

The Xbox 360 Live network is still very much alive, thanks to the Backwards Compatibility of the Xbox One and upcoming Xbox Series X.

In order to transfer your Xbox 360 Minecraft world to a PC, several steps are necessary, but it involves a discontinued version of Minecraft on the Xbox One, so you might not be able to do it at all.

In order to get your Minecraft World transferred, you'll need a Xbox One with "Minecraft Xbox One Edition" (not the Bedrock Minecraft for the Xbox One, that will be the next step).

If you have access to a Xbox One with the "Minecraft Xbox One Edition", start your Xbox 360 Minecraft and make sure it's updated to the latest version.

In Minecraft, upload your world to the Cloud. Then go to the Xbox One and sign in with your Microsoft Account that you use on your Xbox 360.

Start "Minecraft Xbox One Edition", and import your cloud save from the Xbox 360 Minecraft.

Now that you have your world on the Xbox One Edition, let the Xbox One save and upload the save state to the Xbox One Cloud.

After that, start "Minecraft" on the Xbox One (the latest Bedrock version, without the "Xbox One Edition" in the title).

Import your world to the Xbox One "Minecraft".

Now start your free trial for a Realm. Upload your world to your Realm and go to your Windows 10 PC. Sign in with the same Microsoft Account email you used on the Xbox 360 and Xbox One, and start "Minecraft for Windows 10" (the Java Minecraft will NOT work).

Join the realm, and you can download the world to the PC.

Now don't forget to cancel your subscription for the Realm, otherwise you'd have to pay for it.

Turn on xbox start minecraft go to download world and you should find the worlds you saved on windows 10
