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.

To open the registry editor you can either;

• Click "Start", "Run" and type "regedit" and Enter
• or navigate to C:\Windows\regedit.exe

The navigation area of the Registry Editor displays folders, each of which represents a predefined key on the local computer. When accessing the registry of a remote computer, only two predefined keys, HKEY_USERS and HKEY_LOCAL_MACHINE, appear.
