You should be able to delete unwanted software using Control Panel /Add & Remove programs. This should not affect your hidden partition. I would leave that well alone - remember that it is your "escape" if Windows throws a wobbly and you do not want (presumably?) to burn that bridge?
use add remove programs as said above to remove anything you have no use for.the restore floppy should give you two or more restore options to choose from,complete system restore and windows only.
if you choose the former then the computer will be restored to the factory condition you received it in,ie with all the other programs installed.choosing windows only just installs windows without the junk.
have a look in start/all programs/pc tool kit and services/ you may have smart restore,you can use this to install or remove software that comes with packard bells.
