Open the file C:\Windows\my.ini
it should look something like this
Code:
#This File was made using the WinMySQLAdmin 1.4 Tool
#5/21/2004 11:39:14 PM
#Uncomment or Add only the keys that you know how works.
#Read the MySQL Manual for instructions
[mysqld]
basedir=C:/mysql
#bind-address=169.254.101.152
datadir=C:/mysql/data
#language=C:/mysql/share/your language directory
#slow query log#=
#tmpdir#=
#port=3306
#set-variable=key_buffer=16M
[WinMySQLadmin]
Server=C:/mysql/bin/mysqld-nt.exe
user=(username goes here)
