Recently, my Win 98 Registry kept getting restored from an old backup and I had to re-install a networking driver, VPN, and a mail client several times. In evaluating the book's Chapter 40 on the Registry, I asked myself how much it would have helped me solve this problem. If I'd had the book, I would have learned I could restore the Registry from Command Prompt Only mode by running scanreg /restore. This information is not available in Windows Help on the Registry. If I had run scanreg /restore, I would have gotten a choice of backup files to restore and the dates of those files. At that point I would have discovered that one of the backup files was dated five months in the future. In short, the book would have led me to a solution to my problem, so it now has a deservedly prominent place on my bookshelf.
