It's not a simple process to do that, especially if you BOUGHT MS Office along with the PC and it came preloaded -- as the standard HP Recovery Media, which is what you would use to restore your PC, does not contain that.

Your best bet would be to contact HP Customer Support directly and see what they can do for you regarding your getting MS Office in a form that you could reinstall it.
