To look at your processes, threads, modules, network, etc. at a quite low level, you can use the SysInternals Tools. System Internals was bought by Microsoft. So the new site is at Microsoft.com. The old URL still functions though (http://www.sysinternals.com).

Note that since that purchase Microsoft has worked to ameliorate their libraries to give these tools legitimate access to the data they query!

In most cases, these tools work against running processes and not against the source (not the .exe, .dll, etc. files, but their loaded/in memory versions.)
