Remove template help task pane from startup
 

I created an invoice using one of Microsoft's templates. The help template
appeared when I was designing the invoice. Now that the invoice is finished,
I would like for the help template to NOT appear. I went to Tools-Options
and unchecked "startup task pane" and also went to Tools-Customize and
unchecked "Task Pane". This made the task pane go away, but only until I
opened it again. Is there any way to make it not show up every time I open
the document?
