Cant remember anything about my account now I cant get into it

So I made my account something like 7-8 years ago and over that time all I ever use it for is signing up for things like steam xbox youtube etc but over the last year and a half or so I never really used the computer. So when I started installing steam the other day because I wanted to play some games I forgot my password and stem is hooked up to my account so I go and try and log in to my Hotmail and I forgot the password and the security question and the email it was hooked up to so I could recover it is long gone. So now im stuck not being able to access anything because I don't know the security question have no back up email to get the new password and the recover form to reset things says I don't give enough information. Please somebody help me this email is tied to all the accounts I have made over the years and I am basically screwed with out it like is there a Microsoft person I can contact to have it reset or something?
