My windows XP reverted itself to the original settings when I booted a few
days ago. I had to reset everything, including Outlook Express address
book, favorites, start menu items. Thank goodness for backups. It even had
reverted the wallpaper to the big green hill screen. When I started the
computer it asked me if I wanted the Tour of XP. Running Windows XP Pro
which was installed about 5 years ago.

Anyone have any clue why this would happen?

After I reinstalled the missing items everything seems to be working OK.
