        hKey - A handle to an open registry key. The key must have been opened with the KEY_QUERY_VALUE access right.
        dwIndex - The index of the value to be retrieved. This parameter should be zero for the first call to the RegEnumValue function and then be incremented for subsequent calls.
        lpValueName - A pointer to a buffer that receives the name of the value as a null-terminated string.
        lpType - A pointer to a variable that receives a code indicating the type of data stored in the specified value. Registry Value Types
        lpData - A pointer to a buffer that receives the data for the value entry. This parameter can be NULL if the data is not required.
