Somewhat confusingly, the Id attribute of the WIX Product element maps to the Windows Installer ProductCode property.

<Component Id="registry_values" Guid="{11FB6C4C-3C90-4F46-B0D2-BB95150F60E6}">
    <RegistryValue 
         KeyPath="yes" 
         Root="HKCU" 
         Key="Software\MyProduct\Myfolder\SampleFolder\Product" 
         Value="[ProductCode]" 
         Type="string" />
</Component>
