Registry Editor Overview.

Registry Editor is an advanced tool for viewing and changing settings in your system registry, which contains information about how your computer runs. Windows stores its configuration information in a database (the registry) that is organized in a tree format. Although Registry Editor enables you to inspect and modify the registry, normally you do not need to do so, and making incorrect changes can break your system. An advanced user who is prepared to both edit and restore the registry can safely use Registry Editor for such tasks as eliminating duplicate entries or deleting entries for programs that have been uninstalled or deleted.

Folders represent keys in the registry and are shown in the navigation area on the left side of the Registry Editor window. In the topic area on the right, the entries in a key are displayed. When you double-click a entry, it opens an editing dialog box.

You should not edit your registry unless it is absolutely necessary. If there is an error in your registry, your computer may not function properly. If this happens, you can restore the registry to the same version you were using when you last successfully started your computer.
