The left pane of the Registry editor shows the structure of registry keys in the target machine registry. The target machine registry is structured initially into these root keys, or registry subtrees, which are displayed in the Registry editor:
| Root key name | Description |
| HKEY_CLASSES_ROOT | Contains OLE and file-class associations. |
| HKEY_CURRENT_USER | Contains the user profile for the user who is currently logged on, including environment variables, desktop settings, network connections, printers, and application preferences. Use this registry key to differentiate user-specific application settings and information for multiple users using the same machine. |
| HKEY_LOCAL_MACHINE | Contains information about the local computer system, including hardware and operating system data such as bus type, system memory, device drivers, and startup control data. Use this registry key for application-specific information shared among many users on the same machine. |
| HKEY_USERS | Contains all actively loaded user profiles, including HKEY_CURRENT_USER, which refers to a child of HKEY_USERS, and the default profile. Users who access a server remotely do not have profiles under this key on the server; their profiles are loaded into the registry on their own computers. Note The Microsoft recommended best practice guideline is that installer packages rarely write to this registry key. |
