Games for Windows Live and steam games

It seems like an issue on your side. I mean, you're not supposed to make fake emails. They assume you cooperate with them in order for them to be able to cooperative with you, in case of a problem. If I recall correctly, hotmail has the ability of recovering your password to an alternative email, however, it was probably a fake one in your case as well?

Serials are bound to a specific GFWL account, so you will need access to that account.
Maybe you can give the serials (as listed in Steam) to their support and ask the name of the account that registered these serials?

They would not have to legally do anything as you did not provide your true credentials when registering.

That's why always save your account information somewhere . . . I think you pretty much screwed, but I hope you can find a solution with support.

well, that was silly of you for using fake details -.-

So, you don't even know the Hotmail address? Do you know anyone that you emailed from that account that you could ask what the account was called?

/facepalm
