XP Pro Update?

Brother bought a used comp. that has XP PRO installed but appears that it
hasn't been updated to sp2 and windows update won't do it for him. Further,
I was trying to walk him through putting a calendar in the startup folder so
the calendar would open at bootup. He tells me that there is no "all
programs" button on the start menu and consequently he can't open the
"Start up" folder from the start menu. I have XP HOME but have fooled around
with a friends PRO a little and don't remember the two being that different.
Anyone have any ideas??

Thanks
