Can't remember anything.

Well unfortunitly I haven't accessed my hotmail account since approximately 2012 or 2013, it was created around 2011. Since that time no only had I forgotten about the account but all information associated with it except for the phone number I have I possible an associated email account. I need to access that email address. How do I regain access and control?
Thank you for your time. OH and I had a Microsoft Windows Phone at that time.
