First of all, I donβt know why someone refused this question. It was legal, it also happened to me, and I got to this post, trying to find a solution.
Currently, I found it. I created a Windows 8.1 virtual machine in Azure and after providing the username and password, I received the message "Your credentials do not work" when they are provided.
I tried several options, and I finally got enough results by adding the machine name as a domain (since the user I created is local, that makes sense).
eg. if your computer is xpto.cloudapps.net, try registering with "xpto \ username" as your username.
He worked with me.
