The delete operation provides you with a way to clean the registry.  Temporary keys or values left behind by applications can enlarge a profile and reduce efficiency, and by deleting specific keys and/or values, you can regain this lost efficiency.

To create a registry Delete operation, locate the registry item you want to delete, and right-click to bring up a menu of available registry operations.   If you selected a registry key, the Delete Key option can be used or if you have selected a registry value, then the Delete This Value option is available.

In the example below, the Typed URLs under Internet Explorer will be deleted every time the user logs in to a terminal session.
