hp touch smart with windows 8

I recently took the upgrade to windows 8 that hp offered me when I bought my pc.. now that I have it installed I still have a ton of crap from the original install from hp, lime the hp calander, hp games, and a bunch of crap... I can just delete this crap now rite?

if you don't like any of those programs, delete to your heart's content.

your hp came with a restore disc, correct? or something to install windows 7/8 again?
