Processes
What is the system process (PID 0)?
The system process 0 is a place holder for the system idle thread. More information
about the scheduling process and the idle thread can be found in
this sample chapter of Inside Microsoft Windows 2000
IP-Connections
Where can I find more information about the different TCP-states?
More about the different TCP states can be found in the official TCP RFC:
793
Why do I see TCP-connections in TIME_WAIT state?
The TIME_WAIT state is a state that all closed connections enter into. They aren't
shown as associated with a specific process - however during the time the socket
is in TIME_WAIT the specific port can't be reused. The TIME_WAIT is 240 seconds
normally.
To adjust the TIME_WAIT have a look at the instructions and explanations in this
Windows Magazine
article.

Licensing

WMI - Windows Management Instrumentation
What's Running 3.0 uses a Windows technology called
Windows Management Instrumentation (WMI) that has been around for more than
10 years for Windows operating systems.
In rare cases, the WMI subsystem, or parts of it components can become corrupt in
certain Windows installations. The most common WMI problem is that certain classes
(WMI classes) can't be instantiated, resulting for example in an WBEM_E_INVALID_CLASS:Win32_PerfFormattedData_PerfProc_Process
exception. This problem affects all applications using WMI, not only What's
Running.
Diagnosing WMI problems
Fortunately, Microsoft has put together a Diagnostic utility which helps in pinpointing
the problem. In order to understand what is wrong, run
Microsofts WMI diagnostic utility. This tool will output a report, scan
the report for the string "error" and you will find the errors your installation
has.
Fixing WMI problems
There are a few descriptions on the web about how to diagnose and fix WMI problems.
Please note that WhatsRunning.net can NOT guarantee the results of trying to fix
the WMI problems with the approaches described below.
