Forgotten my hotmail password, a reset form didn’t prove successful.

A few months ago I changed my hotmail password and enabled the Save Password feature in Google Chrome, recently when I deleted all my history, cookies etc it also erased the password which unfortunately, I cannot remember. The only thing I can remember was that it was 11 characters long I think, and nothing else. I tried submitting a Password Reset form which did not work since I did not submit enough information to prove the account was mine. I've had this hotmail account for over 5 years now and have around 15,000+ emails, some of which are very important. So I will be very annoyed and angry if I cannot get access back to it.

I'm currently posting this using my friends alternate email.

Thank you for your time.
