You can not hack hotmail account by itself, but if the persons whos hotmail account you want is on the same network, you can easily sniff the password of the account and get in, you can sniff out every HTTP account he logs into, HTTPS will only give you the hash which you can crack, but HTTP will show the password in clear text next to the username in a little program called cain and abel, look at the sticky note at the top of this forum you will see alot of nice sites that is very very useful.
