Removes a value from a specified key.

                                 CAUTION

       Deleting a value results in symbolic links not being
       followed. This is because the system deletes the value
       you specify, even if it has symbolic links.

    This command requires the SYSPRV privilege or the REG$UPDATE
    rights identifier.

    Format:

      DELETE VALUE  key-name value-name
