There have been several posts in regard to the ssh -X/-Y hang, with no

A simplistic work around is to simply not use xauth.exe.  If the port
that the X server is running on (i.e. 6000 by default) is only
available via localhost, this should be reasonably secure vs.
validating individual connections.

Simply make xauth.exe unavailable with a command like:

mv /usr/X11R6/bin/xauth.exe  /usr/X11R6/bin/xauth.exe.nohang

Then forwarding works:

$ ssh -Y target
Warning: No xauth data; using fake authentication data for X11 forwarding.
