bob120579,
WinMySQladministrator and mysql server are two separate things.
WinMySQLAdmin needs username and password not to connect to MySQL but to be able to start it at windoz boot.
I recommend you do not use it at all. It is not needed and it is just one more service running in memory.
Geminidaddy, your mysql service has started, what installation is not complete?
Please give more info.
