Specifies the data component for the specified value. This
    command modifies an existing value.

                                 CAUTION

       Modifying a value results in symbolic links not being
       followed. This is because the system modifies the value you
       specified, not the value pointed to by the symbolic link.

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

    Format:

      MODIFY VALUE /NAME=string  key-name

    key-name

    Specifies the name of the key for which to set the value.
