windows 7 - Suppress OneNote adding itself to startup items

I use the MS Office OneNote app from time to time, but not daily. However, every time I use it, it sticks itself back into the Windows startup items, and helps itself to a chunk of RAM and boot time. Just getting a little tired of pulling up msconfig every time I use the thing. Does anyone know how to keep it from continually sticking itself into startup?

Answer

In OneNote 2010, from the Options menu on the Backstage file tab choose the Display option in the left menu and uncheck 'Place OneNote icon in the notification area of the task bar'.

In OneNote 2007, it is in the "Other" option, not the Display option.
