You see the little verticle line on your quicklaunch bar (or whatever you are using) ?
You just drag that over as far as you want it to go.
If you cant see it, right-click on your task bar and uncheck "lock taskbar".
If you cant drag it over all the way, click and drag the top of the task bar so it moves up one row (makes 2 rows). Then drag your toolbar over and up next to the start button.
Then drag you taskbar down to make one row and the toolbar will be next to it.
I recommend you reenable the locked taskbar to keep from messing it up.
