Over the days I've been using Windows, one thing that most would ignore is bookmark!! I always wasted time rebuilding it. If you're an Internet Exploder freak, it's c:\windows\favorites. I regularly back mine up on another partition. AND I back up the entire Windows partition using Ghost. Ghost can ghost it back in 10 minutes shall anything happen. ANNNNNNNND, I have a habit to back up a fresh Windows install onto a CDRW. So bring the trojan/virus/hackers on. I'm game!
