That's contrary to what I see. Cygwin 1.7 introduced a new way to keep
track of all Cygwin processes, even if they are running under another
user account and in another session. Cygwin 1.5.x was not able to do
that starting with Windows Server 2003.
Consequentially, when running Cygwin 1.7, I see something like this:
$ ps -ef
UID PID PPID TTY STIME COMMAND
corinna 1664 1 con 14:23:49 /usr/bin/tcsh
cyg_serv 1052 1 ? 14:23:55 /usr/bin/cygrunsrv
cyg_serv 3392 1052 ? 14:23:55 /usr/sbin/sshd
corinna 3208 1 con 14:23:57 /usr/bin/tcsh
corinna 936 1664 con 14:24:28 /usr/bin/ps
As you can imagine, the processes running under the cyg_server account
are services running in session 0, while my own processes are running
in the GUI session 2. I see the same output, regardless of running
under UAC or in an elevated shell.
Unless, of course, the processes are running under another Cygwin DLL.
Processe trees running under different Cygwin DLLs are isolated against
each others. They don't share any common IPC objects.
As for `ps -W' output, that's still subject to Windows security
considerations. If you run it in a UAC-controlled shell or under a
non-privileged account, you can only see the processes running in your
own session. If you run it in an elevated shell, you'll see all
processes.
