authenication help on local win32 box

I'm having trouble with my mySQL server on my local computer --

Whenever I type mysql -h localhost -u sano -p
and it asks for the password, and I type it in, it returns with:

error 1045: Access denied for user: 'sano@localhost' (Using password: YES)

My questions:

1. Why does this happen?
2. How can I tell if I ever set a password for this account (I can also access by just using -h and -u without the -p flag)
3. What's the command to change my password?
4. How do I add additional usernames?

Thanks in advance!

Access denied for user error
If you get the error Access denied for user: 'some-user@unknown' to database 'mysql' when accessing a MySQL server on the same machine, this means that MySQL can't resolve your host name properly. To fix this, you should create a file `windowshosts' with the following information:
127.0.0.1 localhost

Here are some URL if you care to read them I believe the MySQL manual will answer all your questions.
