about the username and hostname

Dear everyone:

I start mySQL by a shotcut in windowsXP so that I don't have to input my username, just password is required. That brings in a problem: I don't know my user name(I suppose it to be "root") and the server host, etc. Is there anyway I can find it out? (I suppose the server host is the localhost but I'm not sure)

Thanks very much for any help!

Best Regards,

yours sincerely,
