Connecting a Microsoft Account to Minecraft on PC

No the thing is I have bought the minecraft account with Microsoft and not with a mojang so it was already migrated

And I could login without it connecting with Xbox account and recently it was connecting with my Xbox account and I could not login without saying welkom to you Xbox account (this is on my pc)

Non, j'ai acheté minecraft sur le site minecraft.net, en 2012. Mais comme on peut avoir minecraft sur microsoft store si on a le compte premium, je l'ai relié (avec la clé, etc..). J'arrive jouer sur le minecraft du microsoft store sur mon pc portable,
mais pas sur mon pc fixe.

Je peux vous mettre des screens si vous souhaitez.

my laptop pc, but not on my fixed pc.

I can put screens on you if you like.]

Bonjour, si je comprends bien vous avez acheté Minecraft Premium sur le Marché Xbox avec votre compte Microsoft. Mais vous ne pouvez vous connecter votre compte quand vous voulez y jouer sur PC. C'est bien cela ?

[Translation-Hello, as I understand it you bought Minecraft Premium on the Xbox Market with your Microsoft account. But you can't log in to your account when you want to play it on PC. Is that it? ]

Because you may have redeemed the Minecraft PC bundle code on a different account. Try to check the account that is signed in to your Microsoft Store PC, if it's different from the one you're using in Minecraft then try to check the order history of that account.

Hi there,

-

Disconnecting your microsoft account from your pc account, will allow you to connect via a different microsoft account for each app.

You could also connect the microsoft account with your xbox live account to the pc account.
