This value is calculated differently on Windows- and Unix-based systems.
Under Windows, it uses the call NetWkstaGetInfo(), and takes the value
of the field wki102_logged_on_users. From the MSDN documentation:
wki102_logged_on_users
Specifies the number of users who are logged on to the
local computer.
I've no idea why this might be returning '2' instead of '1'.
Under Unix systems, the relevant code parses the /etc/utmp file,
and returns the number of active entries. A bit of quick testing
seems to show that this lists one "user" for each shell window.
That's probably not unreasonable for a multi-user system accessed
remotely, but is rather misleading for a local ("single user") system
with a graphical desktop. We might need to look again at how this
value is determined.
But that wouldn't affect Windows, since we're using a dedicated API
call to retrieve the value from the underlying O/S.
