The Windows Registry Explained
If you plan to make changes to your Windows registry for whatever purpose, it is vital that you take the time to backup the Windows system registry before proceeding.
Within the registry are a series of values and keys that tell various applications and Windows itself how to behave in a given situation.
A good example of such a situation is how Windows uses the registry to open a Browse dialogue at a particular place. By using a specific entry in the registry, a piece of software can instruct Windows to open the Browse window at a particular folder rather than the default My Computer view.
This is just a basic example of the importance of the registry – which is why it is a good idea to create a backup before proceeding with any adjustments.
