How can I restore a deleted Minecraft Windows 10 Edition world??

Sorry to hear it. If you have deleted your worlds they may be permanently lost. However, if you played on a different system (ie. Xbox) then perhaps the worlds may still exist in the local cache. If you've worked on your worlds that way you should check
it out. If they're not there then I'm afraid there would be no way to recover them.

... 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 truly apologize about this situation AyaanThe0ne your worlds were not support to be deleted. Would you please check this thread here and attempt the steps mentioned there. It could help restoring your worlds. Make sure to keep me updated!

Since the PC was wiped, all locally saved files are gone, so even if you have the Windows 10 version of Minecraft, "restoring previous version" wouldn't work since there is no previous version to restore. (However this could be a solution if you had just
deleted the world and not have wiped the whole PC). Sorry, the world is gone.

If you still can't recover your lost worlds, they are probably gone, so make sure you back up your worlds before uninstalling the game next time. To do so, follow the process described in the link above to access the folder containing all of your worlds
and just copy your saved games anywhere. To restore them, simply paste them in the correct folder and check if they appear in your game. If not, try to follow the procedure from the link to restore your worlds.

I hope this helps you!
