I recently bought minecraft Java and downloaded the launcher, in the Java edition tab it said because I a lready have minecraft Java, I would get the Windows 10 version as a bonus, but when I access the Windows 10 tab I only have the option to download the version of test. Being forced to buy the Windows 10 version. I would like to know how I can access the official version of the Windows 10 version as a bonus, as the text on the right in the attachment says?
 
I'm Brazilian, so the text in the attachment will be in Portuguese.
