In Windows XP the process name for IIS was inetinfo.exe. I don't see it in Windows 7 in the task manager? It seems things have changed. Is it still a separate process?
In Windows 7, w3wp.exe is the process that now responsible for serving the Web sites. Check this out IIS 7 Architecture. By default, there is no Inetinfo.exe process or IIS Admin Service in Windows 7 in fact from Windows Vista onwards.
