well that can depend,
if your the only admin on the Laptop and dont have any passwords for your account then when UEAW promts you for pasword dont type in anything.
if you have more than one admins on your laptop then make sure to select an account that you know the passwords of, in your case it would stay blank.
if you are using Vista then PUT UP A PASSWORD FOR YOU ACCOUNT then install UEAW, it wont prompt you for any paswords. if it does, type in the password and there should be a checkbox thats about always letting your account.
btw, welcome to the UEAW enjoy and most importantly dont drink and post
Thank you,
Fan.
