You asked the same question on StackOverflow group and was told that was not the 
appropriate group - SuperUser is the appropriate StackOverflow group.

It's the MS Windows session number for the first user session.
You can access them using Cygwin or MS Windows directory lookups or tree 
browsers, as I said.
Search microsoft.com for Windows sessions for details about MS Windows APIs.

If you do not yet know that, perhaps you should not yet be digging into these MS 
Windows Executive subsystem objects.

Some of these questions seem very abstract - are these academic questions or 
projects?
