No longer have Minecraft Win10?

On the Mojang account page you could always redeem Minecraft for WIn10 Edition in addition to Minecraft. In the meantime, this is no longer possible and I only have the trial version on the account, although I redeemed the license a few years ago. Is that also the case with you? I would not spend 20 or 30 euro for the poop lol

The Bedrock Edition is only available via the Microsoft Store by default - check if you are logged in to the Microsoft store. Are you using the right Xbox / Microsoft account? Did you link your Mojang account to your Xbox / Microsoft account in any way? Look there first, maybe you are not logged in with the account with which you purchased the Bedrock Edition.

By the way you don't have to pay 20-30 euro for the Bedrock, you can alternatively buy a key. With key resellers like Instant Gaming you can get Minecraft Bedrock for Windows 10 for less than 7 euro, which means that you get it cheaper than the same version on Google Play for your smartphone.

Yes, but I'm using the right account and should have activated the game on it. Every PC Minecraft player has always been able to get a key. I have redeemed mine. I had it recently (a month or two ago). Now the game is gone and the section on the Mojang "My Account" page

Java version can be downloaded from the Mintecraft site - Windows 10 Edition of Minecraft only in the Microsoft store…

Yes I have both. Early there was a redemption function on the Mojang side with which everyone also gets the Win10 version. Now this is no longer possible and I no longer have the game on the account even though it worked a few months ago
