Purchased Multiple Copies Of Minecraft Versions, But Need Minecraft - Java Edition.

Hi Debalena,



Thank you for writing to Microsoft Community Forums.



If you have purchased several copies of Minecraft from Mojang, then I suggest you to refer the
Mojang refunds policy and check their refund policy.



If you want to swap your editions of Minecraft that you have purchased, please
Contact Mojang Support and they will help you with this.



If you have purchased Minecraft from Microsoft Store, then I suggest you to refer
Returning items you bought from Microsoft Store for exchange or refund
and check if you can get a refund.



As you need the Java Edition of Minecraft, you can follow the steps mentioned in
How do I install Minecraft: Java Edition? and install
the Java Edition of Minecraft on your computer.



Before purchasing the Java Edition of Minecraft, I suggest you to refer the system requirements for installing the Java Edition of Minecraft from
Minecraft: Java Edition system requirements.



For reference, you may also refer the Different Minecraft Editions
to know more about the different versions of Minecraft.

 

Java usage to high while playing minecraft/related


We have some confusion going on here.

First of all, the PC edition of Minecraft always used Java, and you will see it using CPU when you run Minecraft. This is normal, and I'm not sure why this is causing the OP to be concerned.

There is a new (Beta) version of "Minecraft for Windows 10" available in the Windows Store. Apparently Mojang converted the code from Java to C++ to run natively under Windows. When this version is running, there should be no Java running. This is not the same thing as the Minecraft PC (or Mac) edition.

If you are running "Minecraft for Windows 10" and you see Java running, it is another application on your system that is using Java. A completely different issue entirely. There are a number of desktop apps that use Java. Crashplan is one example.

 

Java usage to high while playing minecraft/related


Java usage is to high while playing games using java (Mostly Minecraft)

At idle java uses only using about 1-2% CPU usage, but when it comes to playing minecraft it increases to 15%-50%.

When i decrease the amount of FPS Minecraft makes the lower the percentage goes..

Here's a example of me playing minecraft:

OBS- Open Broadcast Software
