Many updates (Windows and otherwise) can't change files that are in use....this is why you get that final dialogue that says you need to restart to complete the update. So the installer "schedules" these changes to occur at the next restart, whenever that is. Once you reboot and the update is complete, that item is removed from the boot schedule. You probably just happened to notice it the one time it should have been there.
If it persists in the boot scheduler and recurs with every reboot, the installation has not completed properly. Assuming that's the Fresco driver, as Yooligan said, I would uninstall that driver and reinstall it.
