I have a new computer (nothing fancy, it's just new and uninfected) which I'm enjoying, and I'd like to keep it that way! I have a pretty good routine of keeping my system up and running, but lack some basic knowledge on what to do initially. For example, I've heard It's smart to create an additional admin account that stays locked and encrypted, unused, so if something bad happens to can just refresh from that point on? Is that considered doing "back up?" I understand backing up photos or music files but not backing up the very beginning of a computers life. Thanks for your help!
