If you send a message to Hotmail Customer Support, the only link I can find is
here they are usually very good at getting access back.
This happend to my account some time ago. I was asked to provide a best estimate of some of the recent emails in my account sent and recieved, some people on my contact list and any information that I could (despite all of this being hacked and changed). They got my account back in under 48 hours.
You could always try "Reset Password" links... however most hackers change the "secret question" too...
Good luck!!
