How too find out what account I claimed my Windows 10 minecraft for free?

Hello Jesus Lozano,

Thank you for posting on the Xbox forums. We understand that you are interested in learning which account you have Minecraft for Windows 10 on. The troubleshooting step that bowski477 recommend is a great option to try with all of your accounts. There
is a section of the Xbox website that shows you the
license for the games that you own. You can try signing in to this website with each account in order to find out which one has Minecraft for Windows 10. Be sure to let us know the results!

If you log into account.microsoft.com and go to your purchase history you should be able to see it listed there.

I did, it doesnt have minecraft windows 10 anywhere listen in there.

Players who have purchased Minecraft: Java Edition before October 19th, 2018 can get Minecraft for Windows 10 for free by visiting their Mojang account. Once you've migrated your account, you will be able to claim a code for Minecraft for Windows 10
