As a long time Windows user you might have heard about
registry. The registry is a special file in your hard disk that
hold most of Windows settings data. Wish to improve your
internet speed or display message at Windows logon? No problem,
those tasks can easily be done by simply editing the registry
value. Unfortunately registry is not a friendly place for most
people. Changing a wrong value in the registry may cause an
unpredictable problem to your Windows. This is why novice users
should not edit registry value directly using a registry editor
by them self.
