You can observe this if you get ProcessExplorer, formerly from SysInternals, now available from Microsoft. (http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx). This tool does not install anything, so you can run it safely on the server.
Each oracle instance shows up as a single process image in the process table, as opposed to *NIX where each oracle background process is a separate entity. On Windows the background processes, server processes, etc. are all threads within the Oracle.exe process image.
Cheers,
