Years ago I bought Minecraft for Windows 10, but now after Java & Bedrock became one it's...

I'd forgot to mention that I had bought Minecraft Java on a different account. But after losing that account I had made a new account. When I switched over, I was given Minecraft bedrock (Minecraft windows 10 edition) not Minecraft Java.

I'm sorry that I wasn't clear. I'm in the same situation as the original poster. I purchased Minecraft back in 2013, so I own what is now called the Java Edition. I recently got a new laptop that is Windows 10; while I had many reservations about Windows
10, the one thing I was looking forward to was being able to finally get the Windows 10 version of Minecraft, Bedrock, so that I could play cross platform with my younger brother, who plays on Xbox. Now, however, I can find no option to redeem my free copy
of Minecraft Bedrock, despite have paid for Minecraft once already years ago.

YES I JUST BOUGHT.

YES. WINDOW IS 10

YES I AM USING SAME ACCOUNT THAT I BOUGHT BUT I CANNOT PLAY BEDROCK EDITION. ON THE BUNDLE TITLE IT SAY MINECRAFT: JAVA AND BEDROCK EDITION BUT WHEN I LOGIN INTO MY MINECRAFT LANCHER I DIDNT SEE BEDROCK EDITION

I'm pretty sure it was for bedrock. Supposedly the code was sent out a while ago, but I have no way of finding it.

Minecraft was never sent as code in a Xbox Live message (unless someone sent you the game as a gift).

And if you redeemed the code, there is no need to search the code anymore, as games you redeem with a code are added to your account. So once you add a game via a code, you will always find it in the "Ready to Install" section of your console, or your Library
on your Windows 10 Store.

If you had the Xbox One Version, you would be able to upgrade to the Bedrock Minecraft on Xbox One for free if you bought the One Version digitally, or played the disc version of Minecraft Xbox One Version for more than 5 hours before February 2018.

But that would NOT give you the Windows 10 Version.

Only if you bought the JAVA Minecraft before October 2018, you would see a redemption button on your Mojang Account website, that would then reveal a code for the Windows 10 Version. That code could then be redeemed on the Windows 10 store to get the Bedrock
Version for Windows 10.

So you could only upgrade from a previous Minecraft on the same platform (i.e. Java -> Windows 10 Bedrock and Xbox One Version to Xbox Bedrock). But you could NOT cross-platform update (from Xbox One to Windows).

I purchased it from minecraft.net Bedrock&Java Edition and it was 29.99 dollars, and I bought it with the paypal.

But I still have the receipt about me purchased minecraft bedrock from year and half ago.
