IIS 7.5 on Windows 7 x64 Ultimate is missing the Management Service icon
Remote Administration against a Windows client SKU (like Windows 7 or Windows Vista) is not supported (WMSVC will not allow connections). That means that the Management Service UI is not required not supported on those SKUs. If you want to allow Web Deploy support to do remote publishing to client SKUs you will need to use the Web Deploy remote service.
This isn't always enabled. You can enable that from Server Manager -> IIS -> Add Roles.
