    '''
    Sets a value in the registry. If ``vname`` is passed, it will be the value
    for that value name, otherwise it will be the default value for the
    specified key

    Args:

        hive (str):
            The name of the hive. Can be one of the following

                - HKEY_LOCAL_MACHINE or HKLM
                - HKEY_CURRENT_USER or HKCU
                - HKEY_USER or HKU
                - HKEY_CLASSES_ROOT or HKCR
                - HKEY_CURRENT_CONFIG or HKCC

        key (str):
            The key (looks like a path) to the value name.

        vname (str):
            The value name. These are the individual name/data pairs under the
            key. If not passed, the key (Default) value will be set.

        vdata (str, int, list, bytes):
            The value you'd like to set. If a value name (vname) is passed, this
            will be the data for that value name. If not, this will be the
            (Default) value for the key.

            The type of data this parameter expects is determined by the value
            type specified in ``vtype``. The correspondence is as follows:

                - REG_BINARY: Binary data (str in Py2, bytes in Py3)
                - REG_DWORD: int
                - REG_EXPAND_SZ: str
                - REG_MULTI_SZ: list of str
                - REG_QWORD: int
                - REG_SZ: str

                .. note::
                    When setting REG_BINARY, string data will be converted to
                    binary. You can pass base64 encoded using the ``binascii``
                    built-in module. Use ``binascii.b2a_base64('your data')``

            .. note::
                The type for the (Default) value is always REG_SZ and cannot be
                changed.

            .. note::
                This parameter is optional. If not passed, the Key will be
                created with no associated item/value pairs.

        vtype (str):
            The value type. The possible values of the vtype parameter are
            indicated above in the description of the vdata parameter.

        use_32bit_registry (bool):
            Sets the 32bit portion of the registry on 64bit installations. On
            32bit machines this is ignored.

        volatile (bool):
            When this parameter has a value of True, the registry key will be
            made volatile (i.e. it will not persist beyond a system reset or
            shutdown). This parameter only has an effect when a key is being
            created and at no other time.

    Returns:
        bool: True if successful, otherwise False

    Usage:

        This will set the version value to 2015.5.2 in the SOFTWARE\\Salt key in
        the HKEY_LOCAL_MACHINE hive

        .. code-block:: python

            import salt.utils.win_reg
            winreg.set_value(hive='HKLM', key='SOFTWARE\\Salt', vname='version', vdata='2015.5.2')

    Usage:

        This function is strict about the type of vdata. For instance this
        example will fail because vtype has a value of REG_SZ and vdata has a
        type of int (as opposed to str as expected).

        .. code-block:: python

            import salt.utils.win_reg
            winreg.set_value(hive='HKLM', key='SOFTWARE\\Salt', vname='str_data', vdata=1.2)

    Usage:

        In this next example vdata is properly quoted and should succeed.

        .. code-block:: python

            import salt.utils.win_reg
            winreg.set_value(hive='HKLM', key='SOFTWARE\\Salt', vname='str_data', vdata='1.2')

    Usage:

        This is an example of using vtype REG_BINARY. Both ``set_value``
        commands will set the same value ``Salty Test``

        .. code-block:: python

            import salt.utils.win_reg
            winreg.set_value(hive='HKLM', key='SOFTWARE\\Salt', vname='bin_data', vdata='Salty Test', vtype='REG_BINARY')

            winreg.set_value(hive='HKLM', key='SOFTWARE\\Salt', vname='bin_data_encoded', vdata=bin_data, vtype='REG_BINARY')

    Usage:

        An example using vtype REG_MULTI_SZ is as follows:

        .. code-block:: python

            import salt.utils.win_reg
            winreg.set_value(hive='HKLM', key='SOFTWARE\\Salt', vname='list_data', vdata=['Salt', 'is', 'great'], vtype='REG_MULTI_SZ')
