I have a remote X application on a Linux system that I want to launch
with a Windows bat file. My main problem is how to determine if Cygwin/X
is running and if not launch it. Once verified I think all I need to do
is use SSH -Y with the command that starts the X application. Can
someone help? TIA.

What about something like:
set DISPLAY=:0
for /f "usebackq delims=" %%A in (`tasklist ^|find /C "XWin"`) do if %%A==0 start C:\cygwin64\bin\XWin %DISPLAY% -multiwindow
c:\cygwin64\bin\ssh -Y 192.168.0.133 xterm
Note that the above bat fails to start XWin if it is already
started with DISPLAY other than :0.

Assuming Cygwin bin is in your PATH, check for xinit base process using
one of the following commands:
$ tasklist /fi "imagename eq xinit.exe" \
Image Name PID Session Name Session# Mem Usage
======================== ======= =============== ========== ============
xinit.exe 2652 Console 1 2,952 K
$ ps -aeW \
37738 37632 37632 2652 cons0 197609 Oct 21 /usr/bin/xinit
$ procps -C xinit \
PID TTY TIME CMD
37738 cons0 00:00:00 xinit
for first two commands, add check for xinit running:
| fgrep -w xinit \
and in all cases, if not, add X start, and sleep 60 or so, to give the X
server adequate time, before starting the remote client:
|| (run --quote /usr/bin/bash -l -c "cd; exec /usr/bin/startxwin"; sleep
60;)
$ ssh -Y $REMOTE $CLIENT
If you want to find the display, try looking under /tmp/:
$ ll -go /tmp/.X*
-r--r--r-- 1 11 Oct 21 09:56 /tmp/.X0-lock
/tmp/.X11-unix:
total 1.0K
srw-rw-rw- 1 0 Oct 21 09:56 X0=
-rw------- 1 0 Aug 18 10:31 X0.lock
