Minecraft - Windows 10 - Error: Invalid Name!

I also had this problem , your screen showing "invalid name"probably and since another player should already be using your gametag on that server or game.

When I logged into windows 10 using my Microsoft account it instantly used my Xbox username. It there any way I can make my Minecraft account different than my Xbox username? This would be extremely helpful, especially because my Minecraft username
is 13 letters, and Xbox usernames can only be 12 letters!

Hi there,

I found this article, I hope this helps:

Minecraft Usernames

This article covers Minecraft usernames for Minecraft: Java Edition on PC/Mac. Minecraft on other platforms do not require usernames, but if you play on Minecraft Realms on these platforms you will use your Xbox gamer tag. The console editions of Minecraft
use Xbox gamer tag or Sony PSN ID.



Where can I find my username?

If you have a Mojang account, your username can be found and changed on your Mojang account page.

Can I change my username?

Users who have a Mojang account (the default account type for all accounts registered after November 2012) can change their username for free at account.mojang.com/me by clicking the
(Change) link next to your profile name.

If you sign in with your username, as older accounts do, you'll first need to migrate to a Mojang account before you can change your username.

I am trying to redeem a Minecraft windows 10 edition key from the Mojang website.

This is the prompt I am trying to redeem from:

Minecraft for Windows 10

You bought Minecraft: Java Edition during a period of time when Minecraft for Windows 10 was included for free. Claim your redeemable gift code by clicking the button below and follow the instructions. As you
might have guessed, Minecraft for Windows 10 can only be played on Windows 10.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

It allows for users who have purchased the java edition of the game to then redeem a code for the windows 10 edition of the game.

This is the error message that pops up:

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Error! It looks like we've temporarily run out of gift codes for Minecraft for Windows 10. Don't worry though, more codes should be on their way. Please check back later!

Thanks for any help!

Hey there,

Is there a specific error code that you get with that error message? It sounds like there may a network issue, or there may be other software installed on your Windows 10 PC that may be interfering with connecting to the game's servers. To start, let's try
uninstalling and reinstalling Minecraft: Windows 10 Edition from your Windows 10 PC. You can uninstall Minecraft from the app list within the Start Menu on Windows 10, and reinstall the game through the Windows Store.

Hope this helps!

Another thing, I can't seem to find the standlone game on the Microsoft Store, only the Starter and Master pack, and I wonder if Minecraft: Windows 10 being removed from the store and being replaced by the packs is causing this issue (as the purchase would be on a invalid item)
