Hi and welcome, I've seen some of your posts to tempestuous, so know you're quite adept for a noob

Unfortunately puppy doesn't [YET] include a 'Useful Tips' section on the opening help screen at the top at first fire-up
The one you need [and will help with changes/restores] is to make a backup copy of your save file - saved elsewhere for recovery by CD bootup...it is possible to have several savefiles with different setups, and get offered a choice which to use when you boot up
Also, in case you fancy using more than one puppy and/or linux/windoze on the same box, see F.E. pemasu's menu.lst tip here
