Thanks.  I followed the link and realized I needed to set a password.  So I followed the link to change the password and managed to follow the instructions for changing the MySQL root password.  However, the stop.bat file I have doesn't stop the server.  I had to restart the computer.  Also, your last instruction "Restart the servers and check access using phpMyAdmin (left menu in apanel)" needs a few more words of explanation because once I get to phpMyAdmin, I don't see anything that tells me where to put the new password.   Nevertheless, I retried the script and it worked.  Thanks again.
